Planning and coordination for decentralised business units in a lumber production company

Abstract : Mathematical models are frequently used in various industries to help decision makers to plan their activities. Many researchers develop planning models for a specific business unit. As an example, the forestproducts industry has access to specialised mathematical models for each production centre of thesawmill (sawing, drying, finishing units) which calls for decentralised planning. In the literature, these models are most of the time evaluated/tested separately, or connected using heuristics and testedin a " static " context (" one shot " demand datasets are provided).In this paper, we want to simulate theuse of these tools by companies for a long period of time (new orders are arriving dynamically, planning need to be updated periodically, etc.).Different coordination mechanisms are compared. We show what the performance of the company would be in terms of accepted orders and average inventory using various coordination mechanisms and order acceptance policies such as available-to-promise (ATP) and capable-to-promise (CTP). Our main finding is that previously published coordination mechanisms for decentralised planning leads to bad CTP implementations which open very interesting research avenues.
