This study addresses a strategic design problem for bicycle sharing systems incorporating bicycle stock considerations. The problem is formulated as a hub location inventory model. The key design decisions considered are: the number and locations of bicycle stations in the system, the creation of bicycle lanes between bicycle stations, the selection of paths of users between origins and destina...

A considerable amount of work has recently been applied to the development of processes to reduce negative environmental impacts of disposal products. Different waste reduction options such as direct reuse, repair, refurbishing, cannibalization, and remanufacturing were introduced to overcome these shortages. This paper studies an integrated system of manufacturing and remanufacturing using a c...

This paper studies a competition in a decentralized supply chain between two independent suppliers who sell their products to a common retailer, under sales-rebate contract, and wherein the demand is sensitive to retail prices. The inventory related operational costs are included in the chain based on the economic order quantity model. The conditions of existence and uniqueness of the retailer’...

Supply chain management is concerned with the coordination of material and information flows in multi-stage production systems. Inventory management has long been treated as an isolated function solely focused on individual entities, taking into account concerned with single-vendor-single-buyer and single-vendormultiple-buyer-models. Concerning the supplier selection problem, quantitative model...

    Discrete facility location,   Distribution center,   Logistics,   Inventory policy,   Queueing theory,   Markov processes, The distribution center location problem is a crucial question for logistics decision makers. The optimization of these decisions needs careful attention to the fixed facility costs, inventory costs, transportation costs and customer responsiveness. In this paper we stu...

Previous researchers have developed ways of managing forward-oriented supply chains, and gave insight to solve single-stage inventory systems. In this study, we analyze an inventory system with traditional forward-oriented material flow as well as a reverse material flow supply chain. In the reverse material flow, the used products are returned, remanufactured and shipped to the retailer for re...

In this paper, a mathematical model for a general integrated lot-sizing and cutting stock (GILSCS) problem is proposed. This model considers multiple dimensions of integration and comprises several aspects found in practice, and as such enables us to classify the current literature in this field. The main classification of the literature is organized around two types of integration. In a planni...

In this paper we study an integrated lot sizing problem with distribution and delivery time windows in which the producer has the choice to locate distribution centers from where products are stored and shipped to customers. Based on a real case study, we describe, model, and solve this rich integrated lot sizing problem. In this integrated optimization application, we consider a multi-plant, m...
