HEURISTIC MODELING FOR A DYNAMIC AND GOAL PROGRAMMING IN PRODUCTION PLANNING OF CONTINUOUS MANUFACTURING SYSTEMS

At the first sight it seems that advanced operation research is not used enough in continuous production systems as comparison with mass production, batch production and job shop systems, but really in a comprehensive evaluation the advanced operation research techniques can be used in continuous production systems in developing countries very widely, because of initial inadequate plant layout, stage by stage development of production lines, the purchase of second hand machineries from various countries, plurality of customers. A case of production system planning is proposed for a chemical company in which the above mentioned conditions are almost presented. The goals and constraints in this issue are as follows： （1） Minimizing deviation of customer＇s requirements. （2） Maximizing the profit. （3） Minimizing the frequencies of changes in formula production. （4） Minimizing the inventory of final products. （5） Balancing the production sections with regard to rate in production. （6） Limitation in inventory of raw material. The present situation is in such a way that various techniques such as goal programming, linear programming and dynamic programming can be used. But dynamic production programming issues are divided into two categories, at first one with limitation in production capacity and another with unlimited production capacity. For the first category, a systematic and acceptable solution has not been presented yet. Therefore an innovative method is used to convert the dynamic situation to a zero- one model. At last this issue is changed to a goal programming model with non-linear limitations with the use of GRG algorithm and that＇s how it is solved.

CHINA'S NON-FERROUS METALS INDUSTRY——Its Development Policies and Goals During the Ninth Five-year Plan Period

The China Non-ferrous MetalsIndustry Corporation has putforward ten development policiesfor the Ninth Five-year Plan period,according to the central government’sinstruction to change the way of economicgrowth,and raise the integral quality andbenefit of the national economy:

Assessment of Land Comprehensive Carrying Capacity in Lin'an City

According to regional characteristics and the actual situation in Lin ’an City, an evaluation index system of land comprehensive carrying capacity composed of three support subsystems （eco-environment, social and economic carrying capaci-ties） containing 22 evaluation indexes was established to evaluate the comprehen-sive carrying capacity of land resource in Lin’an City during 2005-2012. Meanwhile, based on the target data of overal land use plan, the level of land comprehensive carrying capacity was predicted at the end of the plan period （2020） .The results showed that land comprehensive carrying capacity had a significant growth in Lin ’an from 2005 to 2012, and the development trend was basical y sustainable. The sub-systems also had been greatly improved, in which the constant improvement of ec-ological environment carrying capacity made the largest contribution to the constant raising of land comprehensive carrying capacity. The degree of coordination between the systems was poor, in which eco-environment carrying capacity had the maxi-mum growth, far more than the social and economic carrying capacities. According to the land comprehensive carrying capacity in 2020, utilization of land resources in Lin＆#39;an city can achieve sustainable development in general. Final y, proposals of im-proving comprehensive carrying capacity were put forward in terms of the enhance-ment of eco-environment protection, accelerating economic development and policy guidance.

Goal Attainments and the Role of Metacognitive Self in Task Accomplishment

Based on metacognition theories we present a construct of metacognitive self(MCS)as self-awareness of biases.Contrary to counterintuitive idea metacognitive self fosters self-regulation in the area of goal’s attainment.Study 1(N=118)showed that high metacognitive self individuals created more clear mental picture of their plans than low metacognitive self counter partners.Moreover participants high in metacognitive self undertook more actions to fulfill their goals then low MCS colleagues.Study 2(N=201)revealed that high metacognitive self individuals strive for autonomy and they work much better to attain their goals in the no load settings,while low metacognitive students work much better under supervision.

Exploration and development of China's large-scale blast furance

Large-scale BF is the tendency of domestic and foreign Iron-making technology.Due to the limit of resource,technology and equipment,we can not reach the planned goal after putting the big BF into production,it is of great significance to explore the key technologies again for the sound development of the large-scale BF.The paper highlights the unique advantages of large-scale BF and the practical performance of BFs in Baosteel,and explores the related parameter choice,comprehensively matched longevity technology optimization and tapping-stability improvement in terms of structure-design,longevity and equipments etc.The author stresses BF centered basic working regulation,hoping it can exert positive effect on the scientific development of large scale BF in China.

Goals of the Nonferrous Metal Industry Stimulus Plan

Efforts will be made to ensure steady operation in the nonferrous metal sector in 2009,and lay the basis for the industry’s sustainable development by 2011.
