An Optimization Model for Single-Warehouse Multi-Agents Distribution Network Problems under Varying of Transportation Facilities: A Case Study
The transportation cost of goods is the highest day-to-day operational cost associated with the
food industry sector. A company may be able to reduce logistics cost and simultaneously improve service
level by optimizing of distribution network. In reality, a company faces problems considering capacitated
transportation facilities and time constraint of delivery. In this paper, we develop a new model of order
fulfillment physical distribution to minimize transportation cost under limited of transportation facilities.
The first step is defined problem description. After that, we formulate a integer linear programming model
for the single-warehouse, multiple-agents considering varying of transportation facilities in multi-period
shipment planning. We analyze problems faced by company when should decide policy of distribution due to
varying of transportation facilities in volume, type of vehicle, delivery cost, lead time and ownership of
facilities. We assumed transportation costs are modeled with a linear term in the objective function. Then,
we solve the model with Microsoft Excel Solver 8.0 Version. Finally, we analyze the results with considering
amount of transportation facilities, volume usage and total transportation cost.

Taxonomic classification of planning decisions in health care: a review of the state of the art in OR/MS
We provide a structured overview of the typical decisions to be made in resource capacity planning and control in health care, and a review of relevant OR/MS articles for each planning decision. The contribution of this paper is twofold. First, to position the planning decisions, a taxonomy is presented. This taxonomy provides health care managers and OR/MS researchers with a method to identify, break down and classify planning and control decisions. Second, following the taxonomy, for six health care services, we provide an exhaustive specification of planning and control decisions in resource capacity planning and control. For each planning and control decision, we structurally review the key OR/MS articles and the OR/MS methods and techniques that are applied in the literature to support decision making
