One of the hardest problems that limit real application of production system is its slowness. One way to overcome this problem is to speed up the matching operation which occupies more than 90% of the total execution time. In this paper, we try to speed up the matching operation with parallel execution of a typical pattern matching algorithm, RETE, in a multiprocessor environment, This requires not only to make partitions of the rules but also to allocate the partitioned rules to processors, respectively. A partition strategy is proposed to make groups of similar rules by evaluating the similarity of rules according to the number of common conditions between rules. An allocation strategy is proposed to make the load of each processor even by assigning the different priority to the group of rules according to the expected amount of time required for matching operation. To compare with the existing methods, we perform simulation using OPS5 sample programs. The simulation results show that the proposed methods can improve the performance of production system.

The purpose of this study is to determine the effects of production strategies operated by franchisors in the food service industry on the franchisees' culinary competence and subsequently franchisees' satisfaction with performance and recontract intention. In order to accomplish this purpose, two franchised enterprises which used mass-purchasing and mass-producing before distributing to each franchisee for the production strategies were participated and eventually 287 franchisees responded to this survey. Factor analysis and Cronbach's alpha showed the validity and internal consistency for the survey questionnaire. LISREL(8.72) was used to test the relationships between variables; production strategy, culinary competences, franchisee satisfaction, and recontract intention of the franchisees. The results present that the franchisees' satisfaction with the management system, quality of distribution, and quality of foods influenced on differentiation performance and supply performance of franchisees. On cost performance, only satisfaction with the food cost had an impact. The higher franchisee satisfaction with the franchisees' operations was, the higher recontract intention was in the franchise business. The results suggest the critical points for improving foodservice supplying system as well.

Availability of reliable and affordable energy supply is a prerequisite for economic growth. Renewables are the third largest contributor to global electricity production after coal and natural gas and account for a share of 18%. Power generating capacity from renewables has increased to around 900GW by the year 2007. Today biodiesel fuels have been in commercial use in many countries and recently the world-wide biodiesel market has experienced considerable growth, which is partly due to various tax concession programs and other financial incentives. In Korea, biodiesel has already been used for transportation fuel, but not used for power generation fuel yet. Korean government has a strategy for renewable energy propagation, especially the goal of power generation amount by renewable energy is 3% of total power production by 2012. This paper focuses on the feasibility study for adaptability and strategy of using biodiesel as power generation fuel. The study also has the plan to replace the fuel of thermal power plant, gas turbine and distributed power system. As the increase of biodiesel fuel, I look forward to environment-friendly power generation and the strategy of Renewable Portfolio Standards(RPS).

The COVID-19 pandemic weakened the small- and medium-sized enterprise (SME) sector. The decline in turnover is one that is felt by the batik industry in East Java, and the decline in turnover in the batik industry is very drastic. This research was conducted to prove the influence of the COVID-19 pandemic on SMEs in the batik industry. One model is proposed to prove the existence of an increase in the performance of the batik industry's SMEs by implementing a customer relationship management strategy, business strategy, and market orientation. The study population was the batik industry entrepreneurs in East Java, Indonesia, using SEM analysis based on Amos, purposive sampling method, and a sample of 180 respondents. The results showed that the model was accepted. The results also show that customer relationship management and business strategy contributed to the performance of SMEs, while market orientation did not contribute to the performance of SMEs during the COVID-19 pandemic. To be able to maintain the sustainability of the company, the steps taken by the company are to lay off some of the employees, and during the production period the production stops, and focus on selling goods that have been previously produced.

Nash Cournot Equilibrium (NCE) has been widely used in a competitive electricity market to analyze generation firms' strategic production quantities. Congestion on a transmission network may lead to a mixed strategy NCE. Mixed strategy is complicated to understand, difficult to compute, and hard to implement in practical market. However, Stackelberg model based equilibrium does not have any mixed strategy, even under congestion in a transmission line. A guide to understanding mixed strategy equilibrium is given by analyzing a cycling phenomenon in the players' best choices. This paper connects the concept of leader-follower in Stackelberg model with relations between generation firms on both sides of the congested line. From the viewpoint of social welfare, the surplus analysis is presented for comparison between the NCE and the Stackelberg equilibrium (SE).

Ginseng in Korea has not only the big production value but also till a good reputation from overseas in the name of 'Korea Ginseng'. Having spread rapidly nationwide from 2000 year, its production keeps on increasing but its consumption becomes lazy and its price is also falling down because of comsumer's concern about mainly overusing pesticide for ginseng. In order to cope with this problem, the government introduced the GAP certification system to ginseng in 2006 to reflect consumer's needs for food safety. This system will be a good opportunity to promote ginseng consumption dramatically. In this aspect it is very important to know how well this system is established and how ginseng farmers build marketing strategies to draw new wind in the market. This study was carried out to look over the GAP certified ginseng system and show its marketing strategies using 4P's(product, place, promotion and price). The main results are as follows. GAP ginseng system currently has some weaknesses such as lack of systematic certification management and after-service, nonrealistic certification fee and poor linkage from production to consumption. In the marketing mix strategies, product strategy suggests that the most desirable appearance be transplanted ginseng filled with branch roots and 4 to 5 year-ginseng, and it is necessary to choose multi-brand strategy divided for present into for self-sufficiency and family brand strategy by use if its brand enlarges to processed products in the future. In the place strategy, 3 stages like 'producer group' - 'GAP certified facility' - 'sales shop' are based as the physical marketing channel according to traceability, and connected with giant retail market and environment friendly stand, and if its sales volume enlarges, it should be considered the GAP ginseng specialized marketplace which is a type of chain store. In the promotion strategy, the promotion of government level is necessary at first and producer alliances require the promotion targeting at the group of women under 40 with differentiation from price, quality, and safety. In the price strategy, the early stage-high price strategy which sets 20~25% higher for self-sufficiency and 30~35% for present is desirable.
