Syllogix delivers tangible value through the following methodologies of Management Science and Analytics:


Optimization models take into account millions of inputs and determine the best possible decision(s) among virtually innumerable feasible options while meeting your stringent operational and business constraints.

  • 1947 – George Dantzig develops pioneering linear optimization algorithm.

    What is it?

    Optimization is the determination of the ‘best possible’ set of decisions to be taken at any moment in time.

    Operational decision-making problems involve making a set of choices that achieve the best possible outcome (often maximizing profit) while respecting a number of business-rules (e.g. customer requirements, demand fulfillment, etc.), known as constraints.

    To find the ‘optimal’ course of action among all the possible decision combinations requires models with advanced algorithms. Without this state-of-the art mathematics, the sheer number of possibilities would render these types of problems intractable.

    Optimization: Your decision-making intelligence engine.

  • For years, many of the world’s largest corporations have been using optimization models running on supercomputers to help optimize their operations and processes. New technology has leveled the playing-field, allowing any-sized organization to use optimization modeling to:

    • Increase throughput and eliminate bottlenecks
    • Develop intelligent and responsive pricing schemes
    • Create ‘lowest-cost’ staff schedules and timetables
    • Synchronize production scheduling
    • Build risk-balanced asset portfolios
    • Improve customer relationship management
    • Plan floor space and allocate the right mix of product types
    • Manage all aspects of the modern supply chain
    • Bombardier FlexJet to reduce crew levels by more than 20%, while maintaining service levels above 90%.
    • NBC to improve its advertising sales process with optimization-based systems, increasing revenues by $200 M between 1996 and 2000.
    • Ford Motor Company to reduce annual prototyping costs by over $250 M and dramatically shorten the planning process.
    • Canadian Pacific to optimize the routing of rail cars, reducing transit-times and cutting its cost base by $285 M.
    • France Telecom to rapidly react to market changes by updating business rules on the fly, slashing the time required to implement new policies.

    • Data availability and requirements are assessed.
    • The decision-variables, objective function, constraints and their inter-relationships are represented by mathematical formulas.
    • If appropriate, the math is coded into a software model, using powerful optimization modeling environments. This model is then solved by computers and the optimal solution determined.
    • Alternatively, the mathematics may be further studied to determine an optimal policy to be followed under all, or a subset of, circumstances.
    • In linear programming models, sensitivity analyses can be performed to determine the stability of the optimal decisions.
    • Studying the shadow prices can help ‘price’ constraints by determining the value of increasing resource levels.
    • The model can be run with different criteria, to perform ‘what-if’ analyses.
    • Various objective functions can be considered, representing different value judgments.
    • Constraints can be added/removed as required to reflect changing realities or achieve an understanding of the limiting factors.
    Solution Delivery

High-fidelity modeling and a virtual environment in which managers/executives can try out approaches and test ideas before implementing them.

  • Late 1940s – John von Neumann conceives of the idea of simulation to study the effectiveness aircraft bombing.

    What is it?

    Simulation is the virtual modeling of complex real-world systems.

    Many business processes and systems are so complex, with seemingly endless interdependencies and non-linearities, that they cannot be adequately represented using typical mathematical models.

    Simulation is a computer-based tool which generates a virtual environment in which such intricate systems, and the associated uncertainty within them, can be fully modeled and better-understood, in order to make better decisions.

    Using probability distributions to represent the random influences on a system, simulation models are executed for a large number of ‘realizations’. The results are then compiled to gain an overall picture of the expected system behavior. Statistics can be drawn from this data to form conclusions about the likelihood of particular outcomes under various starting conditions and assumptions. In this manner, simulation provides a window into uncertainty and a ‘sand-box’ in which one can try out ideas without disrupting live systems.

    Don’t be overwhelmed by complexity – Gain insight with simulation

  • “The potential of simulation for business process modeling is beginning to be recognized by the business community.” Modern militaries around the world use simulation technology extensively to train soldiers, draft policies and make operational decisions. Increasingly, businesses are learning that simulation can be used in similar ways to improve the way they run their operations and make decisions. Simulation is being used to:

Helping you measure risk, mine data for insights, and make reliable forecasts to predict demand or market trends, and allowing you to better plan your operations and collaborate with your suppliers/customers more effectively.

  • “Firms should budget about one percent of their sales revenues for the forecasting effort.” – Scott Armstrong.

    What is it?

    Forecasting is the estimation of the value of variables at some future point in time.

    Most of us use forecasting on a daily basis when we listen to weather forecasts. This information allows us to better plan our day and prepare for surprises. Business forecasts are even more important for organizations to help plan and manage their operations.

    Business forecasting often uses historical data and is usually performed with the aid of computer software. Forecasting methods can be classified into several different categories: qualitative methods, regression methods, multiple equation methods, and time series methods. Although developing a rudimentary forecast is relatively straightforward, there can be substantial payoff to using (and combining) sophisticated techniques to generate accurate forecasts.

    Plan better using advanced forecasting solutions.

  • Unpredictable demand is in many organizations, their most costly problem. Low forecast accuracy, or no forecast, often results in low service levels, frenzied schedules and poor performance. This costs the organization millions of dollars in safety stock, unneeded inventory, and lead to an unstable Supply Chain.

    Companies that are 30% better at demand forecasting average*:

    • 35% shorter order-to-cash cycle times
    • 15% less inventory.
    • 17% stronger perfect order fulfillment.
    • 10% of the stockouts of their peers.

    Typically, a 1% point improvement in demand forecast accuracy yields a 2% point improvement in perfect order fulfillment capability.

Game Theory

To own and develop your strategy, improve your negotiation performance, resolve and mediate conflicts, map out tactics, and gain the advantage of analyses of multi-participant decision-making scenarios.

  • 1994 – John Nash is given the Nobel Prize for original work in Game Theory.

    What is it?

    Game Theory is the analysis of all possible decision-combinations taken by all participants involved in a strategic issue.

    In many business situations multiple decision-makers (or “players”) with conflicting interests must choose an action that affects both the actions other players may take and the rewards for all parties involved.

    Game Theory is a branch of mathematics that models such situations in order to determine the strategies decision-makers should adopt to best achieve their goals.

    Due to the complexity of the interactions between players, other more traditional decision analyses are insufficient. Game Theory is precisely about making optimal decisions when facing dynamic opponents.

    Stay ahead of the game – Anticipate and influence the actions and reactions of other parties.

  • Traditionally applied by governments and only the largest corporations, advances in computer technology have now leveled the playing field. Professionals today are employing Game Theory models and methodology for:

    • Arbitration
    • Conflict Resolution
    • Labor Disputes
    • Negotiation
    • New Product Introductions
    • Engineering corporate strategy
    • Forming strategic alliances and joint ventures
    • Bidding
    • FCC to perform $7B auctioning of broadcast frequencies & 3rd generation mobile licenses
    • Homeland Security to analyze the risk of future terrorist attacks
    • Hewlett-Packard to develop its framework for an automated Negotiation Support System
    • IBM and Mars Inc. to save Freight Sales $70 million a year through a game-theory based procurement system
    • Major League Baseball to perform salary negotiations
    • US President George W. Bush Presidential Campaign Strategy Team to help win 2 elections
    • Panama Canal Negotiations (1978) to unravel intractable diplomatic entrenchments
  • Consultation
    • Co-client exploration and definition of issues and involved parties.
    • Market/industry experts brought in if required.
    • Co-client selection of scenario and player preference mappings.
    • Define the “scenario state-space” which lists all possible decision-combinations among the parties involved.
    • Preferentially rank decision-combinations according to the goals of each decision-maker.

    Our powerful algorithms conduct and trace Path Analyses (tactics) from the status-quo (the strategic issue as it stands now) to Unilateral Improvements (competitive stance) or Mutually-Beneficial Resolutions (co-operative stance). This provides a step by step means of moving the strategic issue to a predetermined resolution.

    • Equilibria Tests: for identifying the absorbing states (likely resolutions) in the game and the forces that sustain these. These decision-combinations are absorbing states from which no decision-makers would have a unilateral unsanctioned incentive to deviate from.
    • Simulations: for iterative scenario/policy testing

Past Projects

  • The Department of National Defence (DND) of Canada sometimes outsources mission-support services to private contractors to help alleviate strain on the Canadian Forces (CF) in areas where military expertise is less crucial. The challenge for Canadian military planners is to decide upon those missions in which to leverage private contractors, to what extent and in which capacities.

    The Syllogix Solution

    Syllogix was contracted to build a simulation model to support the logistics planning effort of the Canadian Forces. Starting with the current state of CF resources and based on historical and live operational mission data, the model simulates how the current mission requirements might evolve over time and how this, combined with future mission requests, would impact the CF’s need to use private contractors to support its desired international engagements.

    Implemented in a commercial simulation package, and wrapped with attractive and easy-to-use input/output modalities in a spreadsheet format, the Syllogix solution comprises a complete decision-support tool that requires little-to-no modeling expertise to understand and interact with. This accessibility renders the tool even more beneficial to DND since planners at all levels of the organization can more easily appreciate the use of the model and exploit it to study important policy options with respect to mission support planning.

    By running a number of scenarios with different starting assumptions and analyzing the results, CF logistics planners can now answer a number of questions with new-found analytical rigor. For instance, the planning model could be used to study how expanding the Forces over time, combined with accepting a growing mission load, might affect the use contractors over a 5 year planning horizon. Such wide-ranging and multi-faceted questions could only be guessed at without the help of analytical support tools.

    The Syllogix simulation model has augmented DND’s international logistics planning process with objective insight, helping our military decision-makers develop policies that keep our forces strong and safe for years to come.

  • Station Mont-Tremblant, a world-class ski resort and one of North-America’s premiere tourist destinations, needed to better predict the number of snow enthusiasts that will visit its slopes each winter in order to make planning decisions that have financial, operational and customer service related ramifications. Some of these decisions must be made months in advance, others on a much shorter time frame. This makes accurate planning a difficult ongoing problem for the resort’s management team.

    The Syllogix Solution

    Syllogix developed a dynamic and flexible forecasting model, powerful enough to incorporate long-term trends and last-minute effects due to weather, for an all-in-one unified solution.

    The forecasting model constructed by our analysts revolved around well known regression-based techniques, using a large number of 0/1 variables to provide maximal flexibility in the definition of independent predictors.

    A 7 year historical attendance record from the resort formed the dataset upon which the model was run. This time-horizon is long enough for the model to detect economic growth effects over-time, and the important cyclical variations in the data. Due to the fine granularity of the model structure, seasonal holidays (e.g. Christmas, March Break) can be specified by the user so that the model automatically adjusts the forecast appropriately during these peak periods. This functionality allows financial planners at Mont-Tremblant to make long term budgeting and investment decisions for upcoming seasons.

    The model was augmented with the added capability of dynamic revision of the short-term forecast based on weather predictions. The model was made to incorporate daily meteorological data, in such a way that the forecasted attendance values would correctly reflect the influence of similar weather patterns in the past. This added functionality gives the model a great deal more power for performing operational decision-making at the resort (e.g. scheduling correct staff levels).

    In a benchmark test using a year-long hold out sample, the ‘hands-free’ forecasting model was seen to perform at least as well as experienced human executives in the resort’s finance department who were impressed with the accuracy and flexibility the automated solution provided. Work is now underway to further refine the model to become fully integrated into Mont-Tremblant’s financial and operational planning process.

  • Over the past decade, health system administrators in Canada faced a great deal of pressure to do more with less. Governments slashed hospital budgets while the public continued to demand high-quality and timely access to care. Now that governments are beginning to re-establish funding levels, hospital decision-makers must make important choices in regards to how to best allocate resources among surgical programs, so as to most effectively treat patients and reduce overly-long waiting lists.

    The Syllogix Solution

    Syllogix developed for Walker Economics Inc., a respected consultancy in health policy, an embedded optimization model to constitute the core intelligence engine within a complete decision-support tool for health system decision-makers.

    An integer programming model was formulated to select optimal weekly treatment slates, based on the needs of simulated elective surgery patients on waiting lists who must be treated before their Maximum Allowable Waiting Time (MAWT). Taking into account weekly resource allocations defined by the user, the model selects for treatment those patients that are most ‘in need’ of surgery, as calculated by the objective function – which may be arbitrarily customized to reflect operational priorities. Minimum treatment volumes may be defined, by the user, to enforce real-world targets for certain surgical groups. Further limitations may be placed on how specific ‘resource packages’ may be consumed, allowing health administrators study the effect of targeted campaigns or policies.

    By creating different ‘resource schedules’ – defined over a certain number of weeks into the future – the decision-maker uses the software tool to watch how waiting lists can be expected to evolve over time, based on simulated patient arrival volumes. The output of the optimization module (patients to treat each week) is subsequently extracted by the software to compute expected resource utilizations, and waiting lists breakdowns by surgical service and time on the waiting list for each week of a particular ‘run’. Results are then presented in attractive three-dimensional graphs for ease of interpretation and study.

    This patient selection optimization model, was coded into a callable library, and seamlessly integrated into Walker Economics’ enterprise decision-making software. This software, built using a modern web-services paradigm, is now being considered by many health jurisdictions across Canada for implementation.
