物流作为企业的第三利润源泉,越来越多的受到重视,俐氐制造业的生产物流成本.是得到更高利润的有效途径,而物料搬运是生产物流的主要部分,但在企业内并没有受到应有的重视。有效的研究成果更少,它的改善必然会对仓储管理和生产运作起到很好的促进作用。物料搬运信息系统作为物料搬运的重要组成部分,对企业物料搬运信息的传递具有重要意义。本文主要针对制造业企业物料搬运中的问题,设计了物料搬运信息系统,对搬运设备进行了优化设计,从系统的整体构架上对该系统的运行原理与系统组成部分的结构、功能作以详细的介绍。 相似文献

In the majority of small and medium sized enterprises (SEMs), the direct costs of material handling cannot be clearly measured. There are several reasons for this, including the large number of product types, complexity of their production cycle, and continuous change in markets. Therefore, production managers require flexible tools to create a suitable material handling system model which explicitly and rapidly calculates the indices required as these are traditionally neglected or laboriously approximated, (i.e., time and cost in material flow inside the factory, storage area requirements, and MH utilization percentage). This paper proposes an integrated approach to analyzing and controlling material handling operations in an industrial manufacturing plant from a “full quantitative” point of view. The model presented unites quite different fields of research into a unique methodology. This material handling model rapidly and automatically provides production managers with extensive and significant information. As a result, integrated layout flow analysis interrelates systematic layout planning with operational research algorithms and visual interactive simulation, using a complete software platform to implement them. This integrated layout flow analysis approach focuses on determining the space requirement for manufacturing department buffers, the transportation system requirements, the performance indices, and the time and cost of material flows spent in the layout and in MH traffic jams. 相似文献

Markets are affected by strong competition in terms of continuous innovation of products and processes, high customer satisfaction and low cost of production. In order to achieve these strategic results it is recommended, or necessary, to rectify lack of organisation. For instance, the increasing costs due to material handling, force factories to check the facility layout and, when necessary, to improve it. The evaluation of a prospective improvement requires a large effort and a well-established skill. The study and the optimisation of plant layout is a strategic activity. This paper represents the last step of a research program on the automatic design of plant layout. The aim is to support the design activity of plant layout by means of an integrated approach, taking into account many criteria, both quantitative and qualitative. In particular, this paper presents a global approach, based on material flow and activity relationships. It is carried out using new software, called LRP (layout and re-layout program), introduced by the authors. A real application in a factory, specialising in the production of electronic devices, is presented. 相似文献

This paper presents a novel integer linear programming model for designing multi-floor layout of cellular manufacturing systems (CMS). Three major and interrelated decisions are involved in the design of a CMS; namely cell formation (CF), group layout (GL), and group scheduling (GS). A novel aspect of this model is concurrently making the CF and GL decisions to achieve an optimal design solution in a multi-floor factory. Other compromising aspects are: multi-floor layout to form cells in different floors is considered, multi-rows layout of equal area facilities in each cell is allowed, cells in flexible shapes are configured, and material handling cost based on the distance between the locations assigned to machines are calculated. Such an integrated CMS model with an extensive coverage of important manufacturing features has not been proposed before and this model incorporates several design features including alternative process routings, operation sequence, processing time, production volume of parts, duplicate machines, machine capacity, new machine purchasing, lot splitting, material flow between machines, intra-cell layout, inter-cell layout, multi-floor layout and flexible configuration. The objective is to minimize the total costs of intra-cell, inter-cell, and inter-floor material handling, new machines purchasing and machine processing. Two numerical examples are solved by the Lingo software to verify the performance of the proposed model and illustrate the model features. Sensitive analysis is also implemented on some model parameters. An improved genetic algorithm (GA) is proposed to derive near-optimal solutions for the integrated model because of its NP hardness. It is then tested using several problems with different sizes and settings to verify the computational efficiency of the developed algorithm in comparison to a classic simulated annealing algorithm and the Lingo software. The obtained results show the efficiency of proposed GA in terms of objective function value and computational time. 相似文献

In cellular production line (CPL), inter-cell machining and transportation of “exception” parts may lead to equipment sharing, logistic, and process route inter-crossing. More attention paid to such special problems can greatly help solve cellular layout. Based on material logistic analysis, some key technologies orienting CPL layout are studied from the viewpoint of application: (1) material logistic patterns of CPL are modularized, (2) statistic of logistic flow rate on main transportation channels and between machines is presented, and (3) measures of layout adjustment including equipment adding, equipment substituting, equipment sharing, and cell adjustment under the general objective of minimizing logistic cost are analyzed. A numerical example is given, and guiding results for CPL layout are summarized. 相似文献

Design of a robust production facility layout with minimum handling cost (MHC) presents an appropriate approach to tackle facility layout problems in a dynamic volatile environment, in which product demands randomly change in each planning period. The objective of the design is to find the robust facility layout with minimum total material handling cost over the entire multi-period planning horizon. This paper proposes a new mathematical model for designing robust machine layout in the stochastic dynamic environment of manufacturing systems using quadratic assignment problem (QAP) formulation. In this investigation, product demands are assumed to be normally distributed random variables with known expected value, variance, and covariance that randomly change from period to period. The proposed model was verified and validated using randomly generated numerical data and benchmark examples. The effect of dependent product demands and varying interest rate on the total cost function of the proposed model has also been investigated. Sensitivity analysis on the proposed model has been performed. Dynamic programming and simulated annealing optimization algorithms were used in solving the modeled example problems. 相似文献
