承诺交货期过晚,没有时间优势,容易丢失订单;承诺交货期过早,企业超负荷生产,增加生产成本,可能出现亏损。针对基于订单式生产(MTO)的中小制造企业的客户订单交货期预报问题,综合考虑价格、订单需求量、提前完工和延期交货损失、加班、外协和损耗率因素等对任务完工期的影响,以收益最大化为目标,建立了订单任务交货期决策模型,并运用Matlab编程和计算工具对实例进行分析,验证了模型的有效性。模型对MTO生产企业交货期决策具有一定的参考意义。 相似文献

随着市场对定制化设备需求的不断增加,以非标设计制造和单件多品种生产为代表的大规模定制生产模式逐渐被工厂接受,例如水处理设备、造船、核电装备制造业。由于产品设计不断根据客户需求调整,物料和装配方式不能按照流水线方式标准化,供应链长,品质要求高;交货期和成本管理难度大。国际高端水处理设备均被大型跨国公司如GE、西门子等跨国巨头垄断。 相似文献

一、引言 在计划经济向市场经济转换的过程中,企业生产控制的目标也发生了很大的变化。在市场竞争日益激烈的面前,降低成本,加快企业内部的流通,产品按时交货,已经成为企业生存和发展所追求的目标。但是,在传统的生产管理体制下,产品交货期准时率差,生产不均衡,在制品积压较大,工作量的估算误差通常在三分之一左右,以及不断加大的负荷,使制造周期进一步增加,产品交货期一再拖延,致使生产失控,企业生产进入恶性循环,如图1。 相似文献

印铁企业的现场管理--目视管理 总被引:3,自引:0,他引:3
目视管理,是企业生产管理中一种以公开化和视觉显示为特征的管理方式。它主要是利用图表、看板、颜色、物品放置区域规划等工具,把生产现场中发生的问题点、异常、浪费等有关品质、成本、交货期、安全及其它生产活动变成一目了然的状态,营造一目了然的生产和工作环境,借以实现自主管理、自我控制。在产能相对过剩的今天,印铁企业需要从各个方面满足客户的要求,使得企业不得不面对品种多、单个品种的数量少、交货期短的生产状况,从而导致生产现场的管理难度增大。实行目视管理,有助于大幅度提高生产效率,提高产品质量,提高和激励员工的积极性… 相似文献

This paper develops and analyses a stochastic optimisation problem with a service level constraint for generating a sequentially optimal plan of production, maintenance and delivery activities in a deteriorating manufacturing system. Stochastic demand along with product returns are both assumed the latter of which allows for restocking products returned by the customer which are still new and thus in saleable condition. A constrained production/maintenance/delivery problem with service level, stochastic demand, delivery time, failure rate and product returned is formulated based on quadratic model. This quadratic formulation is adapted to provide an inventory, delivery, production and maintenance policies. The objective of this paper is to study the delivery time influence on the planning of the production, maintenance and delivery activities. Finally, we present simulation results to illustrate the exploitation of the proposed approach. 相似文献

As part of general construction management, production planning and control is vital for successful project delivery. Numerous approaches supporting production planning and control exist in practice and research. However, the different approaches focus on distinct areas such as workflow stabilization or cost control, and no single system combines all the requirements of a holistic production management system. Varying production management systems can be explained by the unique characteristics of many construction projects. As an approach for the digital twinning in the construction industry, building information modeling (BIM) can help standardize production management through shifting the management system design toward the digital prototype. Previous scientific work has acknowledged this approach, thereby generating numerous concepts for using building information models within construction management approaches. However, BIM is often merely used as a parallel support rather than as an integral part of production management systems. To address this gap and in terms of research methodology, we follow a Design Science Research approach. Thus, we propose a new BIM-based production management system, which is characterized by a theoretical integration model for BIM and existing construction management techniques, and a methodology for applying these concepts in practice. 相似文献

A joint economic production quantity (EPQ) and delivery quantity model for a production system is investigated in this paper. More specifically, an EPQ policy is implemented in the production system, while a smaller shipping quantity is periodically dispatched to the customer. The production system is also responsible for the shipment cost, i.e. a delivery price-based procurement from the customer. The considered cost includes setup cost to launch the batch production, inventory carrying cost, and transportation cost, where the transportation cost is a function of the delivery quantity. A per unit time cost model is developed and analysed to determine the optimal production and delivery quantities. Under some mild conditions, it can be shown that the joint cost function is convex with respect to the production quantity; and the number of delivery is an integer in each replenishment cycle. Computational study has demonstrated the significant impact of the joint decision model on the operating cost. In particular, the reduction in total cost can be more than 15% when inventory carrying costs, and/or transportation costs, are high. 相似文献

Nowadays supply chain management is a popular practice in manufacturing systems, and just-in-time (JIT) production plays a crucial role in supply chain environments. Companies are using JIT production to gain and maintain a competitive advantage. The characteristics of JIT systems are consistent high quality, small lot sizes, frequent delivery, short lead time, and close supplier ties. This paper presents an integrated inventory model to minimize the sum of the ordering/setup cost, holding cost, quality improvement investment and crashing cost by simultaneously optimizing the order quantity, lead time, process quality and number of deliveries while the probability distribution of the lead time demand is normal. This integrated inventory model is useful particularly for JIT inventory systems where the vendor and the purchaser form a strategic alliance for profit sharing. 相似文献
