Availability allocation is required when the manufacturer is obliged to allocate proper availability to various components in order to design an end product to meet specified requirements. But in designing phase of products, design parameters such as components' failure rate and repair rate are normally under uncertainties. This paper presents a methodology for solving the availability allocation...
Big Data and the popularity of mobile Internet play an indispensable role on the reconstruction of supply chain in China. This article will combine big data, mobile Internet and the supply chain effectively and point out the competitive advantages created by big data and mobile internet from many aspects of time, cost, efficiency, customer experience, etc. Taking warehouse-type supermarkets as an...
In this paper, we propose a variant of the QAP-based facility layout problem: the exclusion facility layout problem (EFLP). Based on Ant Colony algorithm, we design the modified ant algorithm for solving the facility layout problem (FLP). In addition, we also design the ant algorithm for EFLP by increasing the operator of making solution feasible. Analyze the impact of the different parameters values...
Based on the definition of spare parts deployment efficiency, factors influencing of deployment efficiency were analyzed; spare parts fill rate and utilization rate were introduced for measuring spare parts deployment efficiency. Spare parts utilization rate was calculated using Closed Jackson Queuing networks, while spare fill rate was figured out using Dynamic equilibrium equation of Logistics....
In order to analyze the impact of multi-functional support equipment failure, tasks of multi-functional support equipment during maintenance process were described, and maintenance plan of multi-functional support equipment was taken into consideration. Maintenance support process model considering multi-functional support equipment failure was put forward, and thereafter a simulation model was built...
Based on the theory of system dynamics, a dynamic model of various factors affecting the evolution of logistics cluster is established through the casual loop diagram. seven model variables have been identified. To this end, the entry, exit and growth of firms within logistics cluster is modeled and studied with the help of simulations. At last, the paper makes a preliminary numerical experiment....
