Machine cell formation for production management in cellular manufacturing systems

The formation of machine-part families is an important task in the design of cellular manufacturing systems. Manufacturing cell grouping has the effect of reducing material handing cost and work in process. Among the many methods utilized in machine cells formation, the similarity coefficient method is most widely used. Production sequence and product volumes, if incorporated properly in determining the machine cells, can enhance the quality of solutions and reduce the number of intercellular movements. Measures for cell formation based on operations sequence utilizing ordinal production data are few and have many limitations, such as counting the number of the trips for each individual part instead of counting the weights of the batches. A new ordinal production data similarity coefficient based on the sequence of operations and the batch size of the parts is introduced. Furthermore, a new clustering algorithm for machine cell formation is proposed. The new similarity measure showed more sensitivity to the intercellular movements and the clustering algorithm showed better machine grouping.

A New Activity-Based Cost （ABC） Mathematical Model

Along with the product prize competition growing intensely, it is apparently important for reasonably distributing and counting cost. But, in sharing indirect cost, traditional cost accounting unveils the limitations increasingly, especially in authenticity of cost information. And the accounting theory circles and industry circles begin seeking one kind of new accurate cost calculation method, and the activity-based cost ( ABC) method emerges as the times require. In this paper, we will build its mathematical model by the basic principle of ABC, and will improve its mathematical model further. We will establish its comparison mathematical model and make the ABC method go a step further to its practical application.     

低价中标总承包项目成本管理探讨

南港工业区一期东五区吹填造陆工程为设计一施工总承包项目,作为公司在南港工业区经营战略的首个承揽工程,属低价中标。工程中标后,由于预期的外海防护未及时完成,造成工程开工延误。工程开工时,受寒流、大风和冰冻的影响,加上燃油费上涨,导致直接施工成本大幅上涨,成本压力巨大。为扭转亏损,在项目实施过程中,充分利用了“设计-施工总承包”的平台,进行了方案优化和设计细化。同时,在实施过程中,加强现场管理,保证了成本管理目标的实现。项目实施后与原中标成本相比较,节约成本1116．77万元,最后达到扭亏,略有盈余。     

IMEC Industrial Affiliation Program (IIAP) as IPR model to set up nanotechnology research and patenting

The IP policy of IMEC is to avoid IP blocking among its research and business partners, to secure IPR for partners and to enable publications for researchers. This is achieved by setting up a specially designed Industrial Affiliation Program (referred to as IIAP) with licensing and/or co-ownership of IP between the partners. The business IP model applied within the IIAP model at IMEC is characterised by an open, multi-party approach with non-exclusive licensing as a base-line. The IIAP model is further characterized as an IP model in which dilution of IP is minimized in view of further transferability of technology. Using the cost-based and risk sharing approach of the IIAP program, an enhanced progress within new technology domains such as nanotechnology is obtained.

Pricing and lot-sizing decisions in a two-echelon system with transportation costs

We consider a single-buyer single-supplier system. The market demand is sensitive to the selling price set by the buyer. Both the buyer and the supplier operate with unit product costs, inventory holding costs, and order placement costs. In addition, the buyer is responsible for the freight cost. We formulate a model for determining the optimal lot-sizing and pricing decisions. Existing models for the problem do not consider the transportation costs with price sensitive market demand, and determine the optimal decisions through an exhaustive search. We propose an approximate solution procedure, and report the computational results on the effectiveness of the proposed procedure.
