This paper addresses the profitability analysis of 31 chain stores belonging to a hairdressing company in central Taiwan. Four factors are adopted in the analysis with data of year 2010. The 31 stores are classified to four groups according to their levels of return on investment (ROI). The 31 stores are discriminated with apparent rate of 93.5% by a four-group data envelopment analysis-discriminant...
The aim of this study is to compare the predictive performance of feed forward neural network with some of the regression models that are capable of handling certain nonlinear prediction problems. Four real life examples are considered in this study where the response variable belongs to the exponential family of distributions and are modeled using generalized linear models. Results point out the...
This paper aims at using quantified emission limitation as an important indicator when choosing the most optimal scale. Under the limitation of emission, transportation practitioners can buy the allowances from outside market or upgrade systems to conform the standard. In this paper, the related green investment cost and transportation price can be assessed, and the transportation service cost that...
Nowadays, companies should establish a long-term relationship with their customers throughout customer relationship management (CRM). In order to be a winner in the market competition, marketing managers want to maximize customer lifetime value (CLV) and customer equity. So, creating a customer value assessment system is obligatory for companies to identify customers' value, develop strategies for...
Non-additive robust ordinal regression (NAROR), uses primary preferences of decision maker (DM) to define the necessary preference relations (NPR) and possible preference relations (PPR) on alternatives when all compatible fuzzy measures are taken into account and aggregation function is Choquet integral (CI). The question arises as how these NPRs and PPRs can be used in capacity definition problem?...
This study substantially established the evaluation structure of the investment benefit of the Doubling Tourist Arrivals Plan that was divided into five systems including policy planning, government input, international travelers market, domestic economic value and tourism industry development. In addition, the evaluation dimension and secondary dimension of various systems, evaluation indicators...
In this paper, a single-period inventory problem with partially known demand information characterized by possibility distributions is analyzed. Decision models are proposed based on one-shot decision approaches where three choices with considering regret of decision are provided. These three choices are used for determining which state of nature (demand) should be considered for each order quantity...
In the multiple attribute decision making, the computational intensity of problems quickly increases with the number of attributes increases. In this paper, we will introduce the simplification theory and technology of decision matrix in fuzzy multiple attribute decision making, and propose an attribute reduction algorithm. The purpose of this algorithm is to find all of the simplest order-preserving...
Managing multiple brands within a single company is an increasingly important trend in the market. This trend complicates the brand management process. We propose a formal methodology to study resource allocation in brand management systems using Petri nets. Petri nets are a graphical modeling tool that is efficient in characterizing the concurrency of dynamic systems. We focus on an important class...
Efficiency of a Meta heuristic approach depends effectively on the right and suitable choice of its parameters. Meta heuristics are used to develop qualified feasible solutions. They are used while common commercial soft wares can't find exact solutions in a logical computational time. They are random approaches as different target values might be gained during consecutive repetitions of the algorithm...
Under the target of mergers & acquisitions (M&As), in addition to askingthe traditional financial synergy of the maximization of shareholder wealth objectives, it is alsonecessary to think the social care and environmental commitment of social responsibility for the trend of sustainable operation.This paper mainly uses the mathematical model to evaluate how to decide M&As with the sustainability...
MTS-MTO system combines make-to-stock and make-to-order in a sequential manner and deliveries finished products in two steps. The combination system can lower the cost by taking advantage of economy of scale in MTS for standard semi-finished modules production, and satisfy high product variety by taking advantage of flexibility in MTO. But, its performance will drop when capacity is constrained. We...
The prosperous thinking of green environment has changed the perceptions of companies to recognize the whole business operational environment, and how to the maximize stockholders' equity and satisfy the pubic expectation simultaneously is an important subject still waiting to be solved. This paper uses the real options approach to assess the project value reflected by the developing level of green...
This paper develops a Fuzzy-based Integrated Framework (FIF) that responds to the risk of fluctuating demand in a supply chain environment. It is a hybrid framework based on the fuzzy based stochastic demand model and the integrated processes of supply chain in enterprise resource planning (ERP) environment. This proposed FIF can be used to adjust the rate of change of demand based on fuzzy system...
Nowadays companies recognize how important it is to manage their processes so as to increase their productivity and improve the quality of their products and operations. Managers play an important role in this context since they should monitor and improve the processes that are under their responsibility in order to create a competitive advantage for their company. However they do not have the time...
The use of different public policies for certain areas in the same region is a strategic issue for public safety management. Therefore, this article has developed a multicriteria model based on SMARTS method that prioritizes areas for a given region using demographic and socioeconomic issues. It used the “swing weights” procedure to elicit preferences for scale constants. This model was applied in...
