Based on the characteristics of perishable goods, we extend the location-routing problem with distance constraints by adopting chance constrained goal programming approach to solve the uncertainty and to express the different priority levels of decisions. The random of depot construction costs and vehicle routing travel time is taken into account. Meanwhile, a two-stage genetic algorithm incorp...

The article suggests a model for defining rational range and volume of supply perishable goods in their chains functioning at the time random demand. In verbal formulation, goal is to determine delivery volumes that maximize profits with restrictions on funds available purchase, storage weight, as well lost profits. formalized representation determined by properties supplied goods. If these are...

An Agent-based Simulation Exercise Yu Teng, Nan Kong* Weldon School of Biomedical Engineering, Purdue University 206 S. Martin Jischke Dr., West Lafayette, IN 47906 ABSTRACT This paper addresses stochastic dynamic assignment of perishable goods in a scale-free network. We develop an agent-based simulation model in which the supplies and demands for a single perishable commodity are generated at...

We propose a model that integrates inventory routing and freight consolidation for perishable goods with a fixed lifetime. The problem is motivated by the status quo of logistics in some U.S. agriculture markets, but adapts to other relevant two-echelon supply chains, e.g. combined production planning and distribution. We first identify special cases where solving single-echelon subproblems seq...

Intelligent freight objects can be introduced in order to simplify the solution of complex logistical planning tasks. This enables splitting logistical problems to local executable subtasks. The concept of Ubiquitous Computing (UbiComp) presents a model to realize such intelligent objects. A local task can be handled autonomously by a group of objects. The realization of UbiComp needs a platfor...

We analyze the life cycle consumption choice model for multiple goods, focusing on the distinction between durables and perishables. As an approximation of the fact that rather high transaction costs and market imperfections prevail inmarkets for used durables, we assume that investment in durables is irreversible. In contrast to the additive model with one perishable good, the optimal consumpt...
