  • In this paper, we develop two replacement-type reliability acceptance sampling plans(RASPs) for the gamma lifetime distribution assuming that the shape parameter is known. The two plans are respectively based upon failure-free period and hybrid life tests. We then compare the plans in terms of expected test time to reach a decision, power, etc. Computational results indicate among others that the failure-free period RASP has a shorter expected completion time than the corresponding hybrid RASP when the true scale parameter is 'large'. Finally, sensitivity analyses reveal that the effects of the uncertainties involved in the assumed shape parameter on the producer and the consumer risks are in favorable directions for both parties for both types of plans.

  • As the power industry moves towards open competition, there has been a call for methodology to evaluate power system reliability by using composite interruption cost. This paper presents algorithms to evaluate the interruption cost of distribution power systems by taking into consideration the failure source and the composite customer interruption cost. From the consumer's standpoint, the composite customer interruption cost is considered as the most valuable index to estimate the reliability of a power distribution system. This paper presents new algorithms that consider the load by customer type and failure probability by distribution facilities while calculating the amount of unserved energy by customer type. Finally, evaluation results of unserved energy and system interruption cost based on composite customer interruption cost are shown in detail.

  • This paper is concerned with cost analysis model in free -replacement policy under the periodic maintenance policy The free-replacement policy with minimal repairable item is considered as follows; in a manufacturer's view point operating unit is periodically replaced, if a failure occurs between minimal repair and periodic maintenance time, unit is remained in a failure condition. Also unit undergoes minimal repair at failures in minimal-repair interval. Then total expected cost per unit time is calculated according to maintenance period Tin a viewpoint of consumer's. The expected costs are included repair cost and usage cost: operating, fixed, minimal repair and loss cost. Numerical example is shown in which failure time of item has beta distribution.

  • Researchers do not fully understand consumers' responses to negative co-branding events; thus, they report inconsistent evidence regarding the negative impact on the partnering brands. Our research bridges a gap in this research stream, and answers an important question: When a service failure occurs, could the two different models of consumers' brand schema change affect their negative perception of each brand partner? By using a theoretical and mathematical modeling approach, we offer two propositions. The first proposition shows that, under consumers' book-keeping cognitive process, the negative spillover effect occurs for both brands. The second proposition argues that, when the sub-typing model is assumed, it is possible that one brand suffers while the other escapes the blame for the failure. To our knowledge, this is one of the first few studies to identify circumstances in which a negative spillover effect may or may not occur to brand partners in co-branding service failures.

  • This study chiefly aims to examine the relations between customer's responsive behavior and service recovery satisfaction in medical service failure. Therefore, this paper deals with the effect of medical service failure severity perceived by customers on complaint behavior and service recovery expectation, the effect of complaint appealing behavior and service recovery expectation on perceived recovery and service recovery satisfaction, and the roles of service recovery(compensation) and recovery fairness as moderating variables. According to the result of this research, it was shown that service failure severity affects complaint behavior and service recovery expectation positively, and compliant behavior and service recovery expectation affects perceived recovery performance and service recovery satisfaction positively. Moreover, the moderating roles of service recovery(compensation) and recovery fairness indicated partially significant results and affected perceived recovery performance and service recovery satisfaction direct positively. The result of this study is expected to provide support when medical institutes establish service recovery strategies.

  • In this study, we examined whether the intention to choose varies according to the experience of the regret of consumers when experiencing a failure in the status quo or non-status quo, and how self-compassion plays a moderating role in this relationship. A experiment was conducted to achieve the purpose of the study. First, this study also confirmed that regret was a mediator between dissatisfaction with choice outcomes and behavioral intentions. Second, like previous studies, this study confirmed the effect of status quo in general. However, it can be seen that the effect depend on self-compassion. Or, the regrets of those with high self-compassion and their future behavioral intentions did not change significantly whether it was wrong due to maintaining on or changing of the status quo. On the other hand, those with low self-compassion showed the bigger differences, so they were typically showing the status quo effect.

  • The Korean wine market is growing year by year recently especially in Off-trade market. It shows not just a part of the very few consumer-driven trend. The purchases of wine is always not so easy because the risk factors and failure points occur when buying wines. Most of wine consumers feel difficulties when buying wines at phase of previous step, buying step and after buying step. Wine consumers can be divided into the wine experts, wine lovers, novices, outsiders. To guide an wine buying with less failures to each representative of wine consumer characteristics and needs, user persona and scenario for the reduced failure were derived.

  • This paper aims to present colour theories and show how they can be used to explain consumer's preferences of some products over others. It will, furthermore, attempt to link these theories to the design industry and look at how colour associations determine product success. Due to associative learning and personal preference, the colours of objects can cause consumers to either favour or dislike products over those with identical functions and efficiency. Age and gender affect the preferred colour choices of the individual, making some products more popular to particular groups of potential consumers. Designers can utilise colour theories to ensure that they use the most appropriate colour schemes to maximise and appeal to their targeted market successfully. A survey was conducted with 100 participants. It demonstrates the associative links between colours, emotions and product categories. It can be shown that the colour of an object can contribute to its success or failure in the market based on a number of different criteria. The design must use colour confidently to evoke certain emotions or connotations and must be carried out appropriately. The designer also has to consider whom it is that be viewing it and making the decision of preference.

  • Fat in meat greatly improves eating quality, yet many consumers avoid visible fat, mainly because of health concerns. Generations of consumers, especially in the English-speaking world, have been convinced by health authorities that animal fat, particularly saturated or solid fat, should be reduced or avoided to maintain a healthy diet. Decades of negative messages regarding animal fats has resulted in general avoidance of fatty cuts of meat. Paradoxically, low fat or lean meat tends to have poor eating quality and flavor and low consumer acceptability. The failure of low-fat high-carbohydrate diets to curb "globesity" has prompted many experts to re-evaluate of the place of fat in human diets, including animal fat. Attitudes towards fat vary dramatically between and within cultures. Previous generations of humans sought out fatty cuts of meat for their superior sensory properties. Many consumers in East and Southeast Asia have traditionally valued more fatty meat cuts. As nutritional messages around dietary fat change, there is evidence that attitudes towards animal fat are changing and many consumers are rediscovering and embracing fattier cuts of meat, including marbled beef. The present work provides a short overview of the unique sensory characteristics of marbled beef and changing consumer preferences for fat in meat in general.

  • In comparison to the rapid rise in the number of restaurant daily deal service consumer complaints, relatively little attention has been directed at the features of deal consumers' complaint behaviors in academic research. In order to address this gap, this study examined the characteristics of complaint behaviors of consumers who purchase restaurant deals with a focus on three potential determinants (likelihood of success with the complaint, attitude toward complaining, and severity of the failure). Results indicated that the three proposed determinants emerged as critical factors that influence deal consumers to exhibit different complaint reactions to dissatisfactory experiences. Furthermore, it was discovered that the hypothesized relationships were moderated by value consciousness, in which high value-conscious deal consumers exhibited a higher complaint inclination than low-value conscious deal consumers.
