作为成组技巧重要运用之一的虚拟单位制作体系(Virtual Cellular Manufacturing System,简称 VCMS),最近几年来遭到了国际外很多学者的喜爱。虚拟单位制作体系经由过程资本的静态逻辑成组对产物需求变更做出反响,既保存了功效结构的灵巧性,同时又战胜了传统单位制作体系在重置单位物理结构方面的局限性。虚拟单位制作体系的柔性特质,重要得益于其资本同享的灵巧性,再加上多功效通用装备的到来,资本的剖析及设置装备摆设的不适当,常常会形成资本负荷不平衡与资本应用率低的成绩。别的,功课人员也是影响体系灵巧性的一个主要身分,以往的研讨常常疏忽了这一点。是以,将功课人员的身分斟酌出来,同时对资本剖析办法停止研讨,可进步虚拟单位构建的全体机能。本文研讨的 DRC 下基于资本要素的虚拟单位构建成绩,将功课人员视为第二类主要资本,斟酌两重资本束缚(Dual一Resource Constrained,简称 DRC)前提下的虚拟单位构建成绩,并采取了通用的才能单元一资本要素(Resource Elements,简称 RE)来表现资本的自力及共有才能,除能有用处理以上存在的成绩以外,更是完美了RE在VCMSs中的运用,为VCMSs供给了清楚的资本界定,为后续有关VCMSs的研讨任务供给自创,使VCMSs的全体优化加倍可行。 鉴于所研讨成绩的庞杂性,本文试图分两个阶段停止研讨。第一个阶段研讨的是基于资本要素的装备才能剖析的完成进程。将装备的才能分为加工才能和临盆才能,依据多功效装备的加工才能散布情形,借助 SAS 软件的体系聚类剖析,将装备资本的加工才能表现成资本要素集,对装备之间的共有及独有才能停止更明白的描写。有了第一个阶段的研讨基本以后,第二个阶段研讨的是基于资本要素的虚拟单位构建成绩。该阶段在第一阶段的基本上,在两重资本束缚前提下,采取目的计划办法树立了一个多目的数学计划模子,以构建基于资本要素的虚拟单位制作体系,提出的模子使工件、装备、功课人员同时成组并分派至发生的虚拟单位中。斟酌到模子的多目的庞杂性,采取一个多目的忌讳搜刮算法对该模子停止求解,并经由过程数值算例来证实提出模子的有用性。 为验证本文研讨办法在企业中的现实运用情形,本文对某船舶制作无限公司停止了深刻调研,具体剖析了其今朝的临盆治理近况及其存在的成绩,并将本文提出的办法运用在管子加工场的管子加工进程中,提出了响应的虚拟单位构建计划,对改良前后的后果停止了比较,成果显示本文研讨办法的可行性及有用性。

Abstract:

As one of the important techniques using virtual unit group production system (Virtual Cellular Manufacturing System, referred to as VCMS), in recent years was the favorite of many scholars abroad. System through capital process static logic group of product demand changes to respond to making a virtual unit, both to preserve the dexterity of a functional structure, and overcome the traditional production system in terms of the physical structure of a reset unit limitations. Unit of the virtual production system of flexible features, the important benefits in the capital share of dexterity, coupled with the arrival of functions more general equipment, capital analysis and set the equipment, furnishings inappropriate, often form capital load imbalance and capital application rate low grades. Other homework personnel is also a major identity system dexterity, previous research often overlooked this point. So will weigh out homework personnel identity, while the capital analysis method research, can improve the overall performance of virtual construction units. The purpose of this paper is to study the DRC based on virtual units of capital construction achievements, homework personnel will be regarded as the second major type of capital, consider double capital bound dual resource constrained (DRC) under the premise of virtual unit construction achievements and take the general to single element a capital factor (resource elements (re) to the performance of the capital of the independent and total to, except for useful to deal with the above results, it is perfect the application of re in vcmss, for vcmss provides a clear definition of capital, for subsequent vcmss research supply created, vcmss all the optimization is more feasible. In view of the numerous research achievements, this paper is divided into two stages of research. The first stage of the study is to analyze the elements of the capital equipment to complete the process based on. The equipment to points for processing ability and give birth to, according to the multifunctional equipment of processing can be spread, using SAS software system cluster analysis, capital equipment can be processed into capital factor set, of equipment between common and unique to stop more understand the description. The first stage of basic research, the second stage of the study is to construct the virtual capital based on unit performance. The stage in the first stage of the basic, under the dual capital constraints, take objective way to plan set a multi objective mathematical planning model, to build capital elements of the virtual unit based on production system, workpiece, equipment, homework personnel and group and assigned to the virtual unit in the proposed model. Consider to the model of multi objective complexity and take a multi purpose taboo search algorithm of the model is solved, and through numerical examples to verify the proposed model useful. Validate the research methods in the enterprise in practical application, this paper of a ship making Co., Ltd. stop a deep research, analyzes its current birth control situation and existing problems and the way used in pipe processing field of pipe and processing in the process of, put forward a plan to construct the virtual unit response, before and after the improvement the consequences of stopped, the results show that the research methods of the feasibility and usefulness of the.
