This paper demonstrates a method to how reserve capacity and cost allocation could be determined in a pool-based and disaggregated market model. The method considers both the spinning reserve and interruptible loads as the operating reserve services. In the proposed market, generators and consumers (including participation of interruptible loads) submit offers and bids to the independent system...

We consider a make-to-stock supplier who operates a production facility with limited capacity. The supplier receives orders from customers belonging to several demand classes. Some of the customer classes share advance demand information with the supplier by announcing their orders ahead of their due date. However, this advance demand information is not perfect because the customer may decide t...

this paper addresses a production and outbound distribution scheduling problem in which a set of jobs have to be process on a single machine for delivery to customers or to other machines for further processing. we assume that there is a sufficient number of vehicles and the delivery costs is independent of batch size but it is dependent on each trip. in this paper, we present an artificial imm...

Contract manufacturers sell capacity under different terms to different buyers. In a common practice, the supplier offers a market standard price and lead-time combination for products listed in its catalog. At the same time, it strikes contracts with some high-volume customers who require recurring delivery of a custom product at a short notice, usually timed to meet the buyer’s production sch...

Manufacturing companies are facing the challenge to cope with individualized process chains in spite of high market dynamics. In order to achieve high process efficiency by realizing logistic targets, two main leverages can be identified: adjustment of production structure and configuration of production control. The production structure represents the layout and arrangement of machines, the or...

Demand shifting is a popular strategy among service providers for managing demand. The strategy tries to shift demand from peak time periods, where capacity constraints are binding, to offpeak time periods when we have excess capacity. Examples include cities shifting rush hour traffic by having employers staggering work hours; electrical utilities giving their customers timers to shift the sta...

the aim of this paper is to study a multi-product, multi-period production systems in a hybrid flow shop so that lot-sizing and scheduling will be detemined simultaneously. a new mixed-integer programming model is proposed to formulate the studied problem. the objective function in this investigation includes the total cost of production, inventory and external supply. in the case of not satisf...

Abstract. Cloud-computing shares a common pool of resources across customers at a scale that is orders of magnitude larger than traditional multi-user systems. Constituent physical compute servers are allocated multiple “virtual machines” (VM) to serve simultaneously. Each VM user should ideally be unaffected by others’ demand. Naturally, this environment produces new challenges for the service...
