In this paper, the production process management system of minerals processing is established to realize the optimization of the production indices which are inventory of finished ore and capacity of equipment processing. The structure and function of the proposed system are discussed. A multiobjective optimization model is also proposed, and it aims to reduce finished ores inventory and utiliz...
Inventory management and transportation issues are very important problems in distribution companies. Simultaneous l optimization of these problems realizes significant savings for all partners of the supply chain. One of the problems that should be addressed in the scope of simultaneous sl optimization is the inventory routing problem (IRP). IRP deals with how to manage the supply goods from o...
Discrete-event simulation techniques have been widely used for network analysis and policy optimization. In this paper, the use of high fidelity simulation models for real-time control of supply chain interactions is presented. Most formulations for supply chain problems involve optimization of an objective function consisting of various cost components (material, production, inventory, duties,...
Inventory problems generally have a structure that can be exploited for computational purposes. Here, we look at the duals of two seemingly unrelated inventory models that suggest an interesting duality between discrete time optimal control and optimization over an ordered sequence of variables. Concepts from conjugate duality and generalized geometric programming are used to establish the dual...
This paper investigates the integrated optimization of production, distribution and inventory decisions related to supplying multiple retailers from a central production facility. A single-item uncapacitated lot-sizing problem is defined for optimizing production decisions and inventory management. The optimization of daily distribution is modeled as a traveling salesman problem or a vehicle ro...
Most of the studies on inventory control reported in earlier contributions deal with the optimization problems minimizing an expected cost criterion such as the long-run average cost. However, when the plant engineers design the inventory systems in practical situations, they must take account of reliability into the inventory system as well as economical aspect, where reliability can be define...
This paper assumes that the demand is a Poisson random process, the inventory strategy is (s, S), each demand amount Q* is same, scale of the economic transport quantity Q0=p Q* (p is a positive integer), in which Q* is the optimal order quantity of joint pricing used by the supplier and retailer, and the supplier will be entitled to ignore small group of temporary order bills to accumulate the...
Companies survive in saturated markets trying to be more productive and more efficient. In this context, to manage more accurately the finished goods inventories becomes critical for make to stock production systems companies. In this paper an inventory replenishment expert system with the objectives of improving quality service and reducing holding costs is proposed. The Inventory Replenishmen...
The article presents a study on a biobjective generalization of the inventory routing problem, an important optimization problem found in logistical networks in which aspects of inventory management and vehicle routing intersect. A compact solution representation and a heuristic optimization approach are presented, and experimental investigations involving novel benchmark instances are carried ...
This research work develops a decision support model for a network design problem concerning a spare parts closed loop supply chain. It involves the formulation of an optimization model that takes on a mid to long-term planning perspective and covers decisions that have lasting and binding impact on organizational performance. These decisions include investment, location assignment, and invento...
