Production planning policies have a direct impact on demand propagation and the overall performance of manufacturing supply chains. The relationship between production planning and supply chain behavior is important because the planning decisions play a major role in determining how demand propagates through the supply tiers. In this paper, we study supply chain demand behavior via computationa...

This paper proposes a new heuristicmethod for the logistics network design and planning problem based on linear relaxation and DC (difference of convex functions) programming. We consider a multi-period, multi-echelon,multi-commodity andmulti-product problemdefined as a large scalemixed integer linear programming (MILP) model. The method is experimented on data sets of various size. The numeric...

In this paper, we introduce a linear mathematical model for the Aggregate Production Planning problem for a forestry company operating several sawmills. Considering different types of raw materials, different production parameters, and a group of sawmills, the industry tries to identify the best levels of production, of subcontracting production, and of inventory to satisfy the demand for diffe...

in this article, a finite horizon, multi product and multi period economic order quantity like seasonal items is considered where demand rate is deterministic and known but variable in each period. the order quantities of items come in batch sizes and the end of the period order quantity and, consequently, demand of customers are zero. in addition, storage space is constrained and the problem ...

O-Plan is an Artificial Intelligence Planning System written in Common Lisp that has been developed at the University of Edinburgh over the period 1983 to 1999. It is used in a wide variety of applications. It has been deployed as a planning service accessible over the World Wide Web since 1994 and has provided an HTTP interface to users and programs since 1997. It continues to be accessible as...

Today’s product demand and mix changes requiring reconfiguration of cells in each period of a multi-period planning horizon, This paper proposes a mixed-integer non-linear programming model for reconfigurable CMS design to meet changes in product mix & demand in each period of a multi-period planning horizon. The proposed model, to the best of author’s knowledge, is the most comprehensive model...

This paper focuses on a negotiation based collaborative planning process for order pattern determination of multi-period planning in a two-tier supply chain scenario. The aim is to study how negotiation based planning processes would be used to refine locally preferred ordering patterns, which would consequently affect the overall performance of the supply chain in terms of costs and service le...

We consider the multi-period location planning problem of emergency medical service (EMS) stations. Our objective is to maximize the total population serviced by two distinct stations within two different response time limits over a multi-period planning horizon. Our aim is to provide a backup station in case no ambulance is available in the closer station and to develop a strategic plan that s...
