In this paper, we investigate the multiple attribute decision making problems about risk evaluation for risk investment projects with triangular intuitionistic fuzzy information. Then, we proposed the triangular intuitionistic fuzzy Einstein weighted geometric (TIFEWG) operator, triangular intuitionistic fuzzy Einstein ordered weighted geometric (TIFEOWG) operator and triangular intuitionistic fuzzy Einstein hybrid geometric (TIFEHG) operator and we develop an approach to multiple attribute decision making with triangular intuitionistic fuzzy information. Finally, an illustrative example for evaluating the risk of the risk investment projects with triangular intuitionistic fuzzy information is given to verify the developed approach. © Copyright 2016 American Scientific Publishers All rights reserved.

This study investigates the interactions between a manufacturer's information acquisition and quality disclosure strategies in a supply chain setting in which the manufacturer privately knows his product quality but is uncertain about consumer preferences. We argue that the manufacturer should treat his information acquisition and quality disclosure decisions as an integrated process because these decisions can significantly influence a retailer's rational inferences about product quality and can have conflicting effects on his own profitability. Although information acquisition helps a manufacturer subsequently craft better pricing and quality disclosure strategies, it also leaks certain product information to the retailer, thus helping the retailer better estimate product quality. Therefore, in equilibrium, a manufacturer may choose not to acquire any consumer information, even when such acquisition is costless. Moreover, we find that this adverse effect of acquisition is highly dependent on the cost of disclosure and consumers’ preference differentiation. Increased consumer preference differentiation may have a non-monotonic relationship with the manufacturer's profit, and information acquisition can become detrimental to the manufacturer once the disclosure cost is sufficiently high. © 2016 Production and Operations Management Society

Success in web services cannot promise the success in corresponding mobile services. To understand the mobile service adoption behavior under the context of web-mobile service transition, this study, taking mobile eWOM services as an example, investigates the role of trust in mobile service adoption and empirically examines the trust transfer mechanism. Specifically, trust in web services and two relationship-relevant factors namely functional consistency and perceived entitativity are proposed as the predictors of trust in mobile services. A field survey with 235 mobile eWOM services users is conducted to test the research model and hypotheses. The key findings include (1) trust in mobile services positively influences intention to use mobile services; (2) trust in web services, functional consistency and perceived entitativity positively influence trust in mobile services; (3) functional consistency positively influences perceived entitativity. Limitations, theoretical and practical implications are also discussed. © 2012 Elsevier B.V.

Energy consumption in China is continuously increasing. Accordingly, the present paper aims to develop a hybrid procedure for energy demand forecasting in China with higher precision. The mechanism of the affecting factors of China's energy demand is investigated via path-coefficient analysis. The main affecting factors include gross domestic product, population, economic structure, urbanization rate, and energy structure. These factors are the inputs of the model with three forms: linear, exponential, and quadratic. To obtain better parameters, an improved hybrid algorithm called PSO-GA (particle swarm optimization-genetic algorithm) is proposed. This proposed algorithm differs from previous hybrids in the two ways. First, the GA and PSO approaches produce a hybrid hierarchy. Second, two information transfers are accomplished in the process. Results of this study show that China's energy demand will be 4.70 billion tons coal equivalent in 2015. Furthermore, the proposed forecast method shows its superiority compared with single optimization methods, such as GA, PSO or ant colony optimization, and multiple linear regressions. © 2011 Elsevier Ltd.

As an important managerial problem, the practical joint replenishment and delivery (JRD) model under stochastic demand can be regarded as the combination of a joint replenishment problem and traveling salesman problem, either one is an NP-hard problem. However, due to the JRD's difficult mathematical properties, high quality solutions for the problem have eluded researchers. This paper firstly proposes an effective and efficient hybrid differential evolution algorithm (HDE) based on the differential evolution algorithm (DE) and genetic algorithm (GA) that can solve this NP-hard problem in a robust and precise way. After determining the appropriate parameters of the HDE by parameters tuning test, the effectiveness and efficiency of the HDE are verified by benchmark functions and numerical examples. We compare the HDE with the available best approach and find that the HDE can always obtain the slightly lower total costs under some situations. Compared with another popular evolutionary algorithm, results of numerical examples also show HDE is faster than GA and the convergence rate of HDE is higher than GA. HDE is a strong candidate for the JRD under stochastic demand. © 2012 Elsevier B.V. All rights reserved.

The impact of supply chain integration on new product development has been very well studied in literature. However, little literature examines the relationship between supplier integration and customer integration when they influence new product performance. This study aims to explore the complicated relationships among supplier integration, customer integration and new product performance via the mediating roles of manufacturing flexibility and service capability under the trust theory. The research is based on the data from International Manufacturing Strategy Survey (IMSS). It is found that both supplier integration and customer integration had positive direct effects on new product performance. It is also found that supplier integration has a positive impact on customer integration through the mediating role of manufacturing flexibility. The study contributes to supply chain integration by exploring the complicated relationship between supplier integration and customer integration based on the trust theory. It bears implications for both practice and future research. © 2013 Elsevier B.V.

In the real world, some heterogeneous items are prohibited from being transported together or penalty cost occurs when transporting them together. This paper firstly proposes the joint replenishment and delivery (JRD) model where a warehouse procures multi heterogeneous items from suppliers and deliveries them to retailers. The problem is to determine the grouping decision and when and how many to order and delivery to the warehouse and retailers such that the total costs are minimized. However, due to the JRD's difficult mathematical properties, simple and effective solutions for this problem have eluded researchers. To find an optimal solution, an adaptive hybrid differential evolution (AHDE) algorithm is designed. Results of contrastive numerical examples show that AHDE outperforms genetic algorithm. The effectiveness of AHDE is further verified by randomly generated problems. The findings show that AHDE is more stable and robust in handling this complex problem.

In this paper, continuous review inventory models in which a fraction of demand is backordered and the remaining fraction is lost during the stock out period are considered under fuzzy demands. In order to find the optimal decision under different situations, two decision methods are proposed. The first one is finding a minimum value of the expected annual total cost, and the second one is maximizing the credibility of an event that the total cost in the planning periods does not exceed a certain budget level. For the first decision method, an approach of ranking fuzzy numbers by their possibilistic mean value is adopted to achieve the optimal solution. For the second one, the technique of fuzzy simulation and differential evolution algorithms are integrated to design hybrid intelligent algorithms to solve the fuzzy models. Subsequently, the two decision models are compared and some advices about inventory cash flow management are given. Further, sensitivity analysis is conducted to give more general situations to illustrate the rationality of the management advices. © 2011 Elsevier Ltd. All rights reserved.

The aim of this study is to select airline service quality improvement criteria for the Taiwanese airline industry. Numerous factors such as low railway prices, the development of high-speed rail, increases in petroleum prices, increases in foreign airline competition, and the recent economic depression have led many airlines in Taiwan to encounter financial difficulties and even closure. Researchers have begun to identify critical service quality improvement criteria with the goal of increasing the competitive advantages of airlines. Most of the selected criteria, however, suffer from a major technical problem: all of the measurement dimensions are independent, leading to inadequate criteria for measuring service quality. Our calculations consider the interrelationships and effects among the evaluation dimensions and criteria to precisely rank and select criteria. The value of this study is that it provides airlines with a direction for measuring and improving their service quality with the goal of developing sustained competitive advantage over the long term. © 2016 Elsevier Ltd
