In this work, we consider a multi-period inventory model with raw material procurements done via a reverse auction. Bids are multi-dimensional and they consist of supplier information of price, shortage quantity and lead time. This work is an extension of our earlier work that has integrated single-period inventory models with multidimensional procurement auctions to multi-period settings. The ...

This research proposes a mathematical model in piecewise objective integer with quadratic programming to accommodate discount purchase, holding and transport costs on an integrated inventory control supplier selection problem. The proposed can be used determine the optimal decision, specifically, quantity of product ordered by decision maker stored should have minimal effect total cost. To eval...

    Dynamic cellular manufacturing systems,   Mixed-integer non-linear programming,   Production planning, Manufacturing attributes   This paper presents a novel mixed-integer non-linear programming model for the design of a dynamic cellular manufacturing system (DCMS) based on production planning (PP) decisions and several manufacturing attributes. Such an integrated DCMS model with an extensi...

Inventory levels are critical to the operations, management, and capacity decisions of inventory systems but can be difficult to model in heterogeneous, non-stationary throughput systems. The inpatient hospital is a complicated throughput system and, like most inventory systems, hospitals dynamically make managerial decisions based on short term subjective demand predictions. Specifically, shor...

developing an integrated model, establishing a balance between conservation and revitalization objectives in the historic environment, has always been a controversial issue in many countries; however, they sometimes have a type of symbiotic relationship with each other. in this regard, the main aim of this paper is to answer this question: is it possible to provide an appropriate model for “int...
