THIS STUDY AIMS TO IDENTIFY AND PRIORITIZE THE APPROPRIATE LOCATIONS OF TOURIST VILLAGES, WHICH ARE ENABLED FOR HEALTHCARE ACTIVITIES, IN ISFAHAN PROVINCE, IRAN. IT IDENTIFIES FACTORS AFFECTING THE DEVELOPMENT OF THESE VILLAGES AND ALSO TAKES INTO ACCOUNT THE CHARACTERISTICS OF PASSIVE DEFENSE. FIRST, CRITERIA AND SUB-CRITERIA RELATED TO PROPOSED LOCATION DECISION HAVEBEEN IDENTIFIED USING LITERATURE TOGETHER WITH EXPERTS’ OPINIONS, AND THE PAIRWISE COMPARISON QUESTIONNAIRE HAS BEEN DESIGNED. A PANEL OF EXPERTS AND PRACTITIONERS IN THE FIELD HAVE BEEN INVITED TO COMPLETE THE QUESTIONNAIRE AND SUBSEQUENTLY THE WEIGHT OF EACH COMPONENT HAS BEEN CALCULATED. THEN, BASED ON THE PRIMARY GEOGRAPHICAL DATA PREPARED BY DIFFERENT ORGANIZATIONS AND USING GEOGRAPHIC INFORMATION SYSTEM (GIS), DATA LAYERS IN THE ARCGIS SOFTWARE HAVE BEEN CREATED AND THE APPROPRIATE LOCATIONS IN ISFAHAN PROVINCE WERE IDENTIFIED. FINALLY, USING THE ANALYTIC HIERARCHY PROCESS (AHP) AND THE WEIGHT OF EACH LOCATION, THE RANKING PROCESS HAS BEEN APPLIED AND THE MOST APPROPRIATE LOCATIONS HAVE BEEN EXTRACTED.

IN THE PRESENT WORK, A VARIATION OF THE CLASSICAL FLOW-RACK AUTOMATED STORAGE AND RETRIEVAL SYSTEM (AS/RS) IS INVESTIGATED. THIS CONFIGURATION IS USING A SINGLE STORAGE AND RETRIEVAL MACHINE INSTEAD OF TWO MACHINES DEDICATED TO STORAGE AND RETRIEVAL. THE AIM BEING TO REDUCE THE CAPITAL INVESTMENT OF THE WAREHOUSE. THE PRESENT PAPER AIMS TO INVESTIGATE TRAVEL TIMES MODELS OF THIS SYSTEM. EXACT DISCRETE TRAVEL TIMES MODELS ARE DEVELOPED AND USED TO VALIDATE THE APPROXIMATE CONTINUOUS MODELS DEVELOPED BY AUTHORS IN PREVIOUS WORKS. THESE EXACT MODELS ARE DEVELOPED FOR STORAGE, RETRIEVAL SINGLE CYCLES AS WELL AS FOR DUAL CYCLES. IN ADDITION, TWO DWELL POINT POSITIONS OF THE STORAGE AND RETRIEVAL MACHINE ARE INVESTIGATED. AN OVERALL TRAVEL TIME MODEL CONSIDERING SINGLE AND DUAL CYCLE OPERATIONS IS PROPOSED. COMPUTER SIMULATION IS USED TO COMPARE EXACT AND APPROXIMATE TRAVEL TIMES MODELS FOR DIFFERENT SCENARIOS OF THE AS/RS DIMENSIONS.

ONE OF THE ISSUES OF REDUCING WASTE AND THEREFORE INCREASING PRODUCTIVITY IN MANUFACTURING ENTERPRISES IS TO ENDOW WITH SMOOTH AND GOOD PRODUCTION LAYOUT. ORGANIZATIONS CAN MAKE PRODUCTION FLOW LAYOUTS PRODUCTIVE BY FOLLOWING UP LEAN THINKING MODEL, THEREBY PRODUCING FINAL PRODUCTS WITH MINIMAL WASTE. THE PURPOSE OF THE RESEARCH IS TO PROVIDE A MODEL TO AIDINDUSTRY MANAGERS’ DECISION-MAKING PROCESS WITH CHOOSING BETWEEN THE MOST APPROPRIATE PRODUCTION FLOW LAYOUT PATTERNS WITH RESPECT TO THE AMOUNT OF WASTE IN PRODUCTION UNITS; HENCE THE IDEA IS TAKEN CARE OF BY CONSIDERING CRITERIA OF INVENTORY LEVEL, TRANSPORT, LEAD TIME AND PRODUCT QUALITY. IN ORDER TO EVALUATE AND CHOOSE LAYOUTS BASED ON THE FORGOING CRITERIA, A FUZZY INFERENCE SYSTEM WAS EMPLOYED. THE SYSTEM INPUT IS RATING OF EACH LAYOUT OF PRODUCTION FLOW FOR EACH CRITERION, WHICH WAS OBTAINED BY AHP METHOD, AND ITS OUTPUT IS THE AMOUNT OF WASTE OF EACH LAYOUT OF PRODUCTION FLOW. IN ORDER TO SIMULATE THE PROPOSED FUZZY INFERENCE SYSTEM, MATLAB SOFTWARE WAS UTILIZED. IN THE END, A PRODUCT LAYOUT WITH A QUANTITATIVE DIFFERENCE COMPARED TO GROUP (CELL) LAYOUT, TOOK UP THE LEAST AMOUNT OF WASTE AND WAS CONSIDERED AS THE MOST SUITABLE OF LEAN PRODUCTION FLOW LAYOUT FOR THE STUDY FIRM.

THE BETTER PATTERNS FOR CONSUMPTION ARE WIDELY SPREAD ALL OVER THE WORLD THEN THE GENERAL DISCUSSION ABOUT SUSTAINABILITY IS CONSIDERED IN DIFFERENT ASPECTS OF LIFE. MANY COMPANIES TODAY APPLY THE CONCEPTS OF SUSTAINABILITY IN THEIR MANUFACTURING PROCESSES FOR SURVIVING AND IMPROVING THEIR BUSINESSES. MANY RISK FACTORS CAN DECREASE THE CHANCE OF SUCCESS IN BUSINESS AND SPEND LOTS OF TIME MANAGING. IN A MORE GENERAL PERSPECTIVE, SOME CRITICAL FACTORS CAN IMPROVE THE PROCESS OF MANUFACTURING. ALTHOUGH THE DIMENSIONS OF MANUFACTURING SUSTAINABILITY ARE NUMEROUS, IN THIS STUDY WE TRY TO REVIEW SOME MAJOR FACTORS WHICH CANNOT PASS AWAY SIMPLY FROM IT IN EACH STUDY. THIS PAPER DESCRIBES THE SUBSTANTIAL AREAS IN SUSTAINABILITY SUCH AS: ECONOMIC PERFORMANCE, ENVIRONMENTAL ASPECT, SUSTAINABILITY ASSESSMENT, DIRECT DIGITAL MANUFACTURING AND THE USE OF SUSTAINABLE SUPPLY CHAIN. KNOWING ABOUT THESE FACTORS CAUSE TO INDUSTRIAL DEVELOPMENT. BY AGGREGATING THE SET OF POINTS OF THIS STUDY, THE WAY OF FUTURE EXECUTIVE RESEARCHES WILL BE MORE CLEAR AND IDENTIFIED.

WHILE THE POSITIVE RELATIONSHIP BETWEEN BETA OF A STOCK AND ITS FUTURE RETURN IS IMPLIED BY CAPM, EMPIRICAL LITERATURE DOES NOT SUPPORT THIS PROPOSITION. THE RECENT ADVANCEMENTS IN RISK-RETURN RELATIONSHIP HAVE DOCUMENTED THE BETA ANOMALY, OR BETTER STILL BETTING AGAINST BETA, AS THE MOST COMPLICATED ANOMALY IN FINANCE. IN THIS PAPER, THE AUTHORS STUDY THE ROBUSTNESS OF BETTING AGAINST BETA PHENOMENON IN THE STOCK MARKET VIA INVESTIGATING IT ON ABSOLUTE RETURN AND RISK-ADJUSTED BASIS USING US MARKET DATA OVER THE PERIOD 1984-2012. TO DO THIS, BETA-SORTED QUINTILE PORTFOLIOS ARE USED TO ESTIMATE BETA BESIDE FOUR MULTI-FACTOR MODELS. THE RESULTS OBTAINED PROVIDE EVIDENCE FOR EXISTENCE OF BETTING AGAINST BETA ON RISK-ADJUSTED BASIS ONLY. IMPLICATIONS, DISCUSSION, AND FUTURE RESEARCH DIRECTIONS ARE DISCUSSED AT THE END OF THE PAPER.

THE EVER-INCREASING PRESSURE OF COMPETITIVE BUSINESS ENVIRONMENT FORCE THE BUSINESSES TO KEEP THEIR COMPETITIVE ADVANTAGES THROUGH DIFFERENT STRATEGIES. ESPECIALLY, SERVICE-PROVIDING BUSINESSES STRIVE FOR KEEPING AND INCREASING THEIR MARKET SHARE THROUGH CUSTOMER SATISFACTION MONITORING AND IMPROVEMENTS. IN THIS RESEARCH, ELECTRONIC BANKING SERVICES (EBSS), PROVIDED BY A BRANCH OF AN IRANIAN BANK, ARE IDENTIFIED AND RANKED BASED ON CUSTOMER SATISFACTION. IN ORDER TO ACHIEVE THE GOALS OF THIS RESEARCH, THE CHANNELS OF ELECTRONIC BANKING SERVICES ARE IDENTIFIED AND A QUESTIONNAIRE IS DESIGNED TO MEASURE THE CUSTOMER SATISFACTION LEVEL FOR THE SERVICES FOR THE SUMMER 2015 TIME PERIOD. THE DATA ARE ANALYZED BY SPSS AND MINITAB SOFTWARE PACKAGES AND THE OBTAINED RESULTS SHOW THAT AMONG SIX TYPES OF IDENTIFIED SERVICES, INCLUDING AUTOMATED TELLER MACHINES (ATM), PHONE BANKING (PB), INTERNET BANKING (IB), MOBILE BANKING (MB), WEB KIOSK (WK) AND POINT-OF-SALES TERMINAL (POS), THE CUSTOMERS WERE MOST SATISFIED BY THE ATMS AND LEAST SATISFIED BY THE WK. IN ORDER TO FACILITATE DECISION MAKING REGARDING THESE EBSS, SOME MANAGERIAL IMPLICATIONS AND SUGGESTIONS BASED ON THE RESULTS ARE ALSO PROVIDED; HOWEVER, THIS RESEARCH WAS LIMITED TO THE DATA OF A BRANCH OF A BANK AND THEREFORE, GENERALIZATION OF THE RESULTS SHOULD BE EXERCISED WITH CAUTION.
