BP神经网络误差修正的电力物资时间序列预测

传统的ARIMA时间序列分析方法是基于线性技术来进行时序预测,而对非线性数据的处理不尽合理,效果欠佳;而影响电力物资需求的因素非常多,绝大多数的物资序列通常既包含了线性时序的部分,又包含了非线性时序的成分.本文提出在ARIMA对电力物资需求预测的基础上,融合BP神经网络进行误差修正,以全面提取物资序列中的复合特征,提高电力物资的预测精度.实验结果表明,误差修正后的电力物资预测精度有了显著提高,可以为制定物资采购计划提供重要的数据支持.

An integrated multi-stage supply chain inventory model under an infinite planning horizon and continuous price decrease

This paper studies an integrated inventory model in a supply chain that involves procurement, production and delivery activities. The model is studied in an environment where products experience continuous price decrease and planning is performed in an infinite time horizon. In this model, a manufacturing facility purchases a fixed-quantity of raw materials from an outside supplier, processes the materials, and delivers a fixed-quantity of finished products to a customer periodically. In order to take advantage of the decreasing price trend, customers demand frequent deliveries of small lots of finished products, and this inventory management strategy has been used by many successful companies in technology-related industries. Therefore, the ultimate intention of this research is to study and model the inventory system for high-tech companies whose products are experiencing continuous price decrease. This model is used to determine an optimal economic lot size model for raw material procurement, production setup and finished goods delivering under an infinite planning horizon. Two efficient algorithms are developed in this paper to solve this nonlinear model and the test results consistently indicate that ordering of raw materials and delivery of finished goods should be frequent in small lots for low ordering and shipment costs. Finally an operational schedule is provided to show the implementation procedure of the model.

Finite horizon planning for a production system with permitted shortage and fixed-interval deliveries

Raw material ordering policy and the manufacturing batch size for frequent deliveries of finished goods for a finite horizon plays a significant role in managing the supply chain logistics economically. This research develops an ordering policy for raw materials and determines an economic batch size for a product in a manufacturing system that supplies finished products to customers for a finite planning horizon. Fixed quantities of finished products are delivered to customers frequently at a fixed interval of time. In this model, an optimal multi-ordering policy for procurement of raw materials and production cycle time for a two-stage production and supply system is developed to minimize the total cost incurred due to raw materials and finished goods inventories. The problem is then extended to compensate for the lost sales of finished products. A closed-form solution to the problem is obtained for the minimal total cost. A lower bound on the optimal solution is also developed for problem with lost sale. It is shown that the solution and the lower bound are consistently tight.     

Least cost estimating with group technology

A twenty-two digit alpha-numeric Group Technology System was established for the Aerospace Group of VSI Corporation. In addition, the planning for least cost processing planning generation has been completed using the Group Technology (G.T.) System. The G. T. System is also being used for the classical applications such as tooling, reduced set ups, process plans, identifying duplicate parts, etc., in addition to the planned least cost method. The least cost method uses a unique empirical production standards system in conjunction with the G. T. Code for its implementation.     

Evaluating supply partner’s capability for seasonal products using machine learning techniques

We develop a dynamic partner assessment system (DPAS) in order to assess change in a supply partner’s capability over a period of time. The system embeds a multi-criteria decision model and machine learning methods, and is designed to evaluate a partner’s supply capability that can change over time and to maximize revenue with different procurement conditions across time periods. We apply the system to the procurement and management of the agricultural industry. The results are compared with real-world auction markets.

Close-optimal production and procurement policy for a X-network of added value using lexicographic linear goal programming

One of the main challenges of operation managers of firms is to setup feasible production and procurement plans. This is also the case of more complex structures such as supply chains. In almost all firms, specific tools like ERPs are used to support managers in their decision-making tasks. These tools manipulate huge amount of data such as the order backlog, or technical, marketing, suppliers and customers data. They work often based on the MRP principles and suggest production and procurement plans after a sequential procedure which begins by the material requirements calculation followed by the load balancing process. Very often, the load balancing is under the control of managers who try to take account of implicit constraints that cannot be modelled easily. This is a difficult and often risky task because the managers do not know what the best solution of the planning and procurement problem is. In other words, there is a lack of a kind of “the best feasible production and procurement target”. The main idea of this article is to suggest a complementary method for planning based on a specific mathematical programming approach which provides plans considering simultaneously all material and capacity constraints over the entire planning horizon. These plans can be considered as that necessary closed optimal production and procurement target for a company or a supply chain which uses an MRP-based planning tool. The lexicographic linear goal programming provides a suitable multi-criteria modelling paradigm for the production and procurement planning problems, especially for the supply chains. The study is focused on a common supply chain structure formed by several suppliers on one side and several customers on the other, connected together by a business-to-business relationship over a rolling horizon. The structure is modelled thanks to the Petri Nets supporting the definition of the global problem model. The model is then applied to a study case extracting from the car assembly industry.
