Data Envelopment Analysis (DEA) evaluates a large number of input and output variables using mathematical programming techniques and analyzes the effectiveness of similar decision making units (DMU). Unlike traditional methods, the most important advantage of DEA is that the weights of input and output variables can be defined by the analyzer. In this study, the limitations of the DEA weights were determined using the AHP, which considers expert opinion. In addition, an alternative judgment scale was used for the Saaty judgment scale, which is used as a standard in the AHP method, and thus a more sensitive analysis was performed. There have been studies dealing with the comparison of judgment scales, but few studies on consistency sensitivity are needed. This point has also been addressed in this study. Subsequently, the financial efficiency of 27 companies operating in the food sector in Kosovo was evaluated with the weight-restricted DEA model, first created using the unweighted DEA model and then the AHP model, and the two models were compared. This paper is the first one of its kind since there are no previous studies regarding the examination of the financial efficiency of companies operating in the Kosovo food sector based on the DEAHP method.

“…QFD is the transformation of consumer needs (whats) into technical requirements (hows) at every phase of product development and production. QFD associates customer expectations with technical requirements and uses the house of quality (HoQ) matrices to demonstrate the quality of projects and achieve the objectives [20,38]. Upon completion of these matrices, the QFD process usually ends [39].…”

The aim of this investigation was to help select design criteria that highlight customer satisfaction, and thus improve the design quality in buildings, specifically in a building of a thermal hotel. The methodology is based on applying the Quality Function Deployment (QFD) technique to listen to the voice of the customer, in addition to the Analytic Hierarchy Process (AHP), which allows selection of the best design alternative. The literature shows that QFD–AHP methods have been tried in different areas of the building industry, but there are few examples of combining building design processes. In the study process, collaboration environments between stakeholders were established and the operability of the method used was tested with real actors. The matrix solutions realised in the horizontal and vertical sections of the framework of the model can be reused in different projects with different user demands. This added a modular and developable feature to the model. This study revealed that the most important customer needs, in order of importance, are “health”, “service”, “comfort”, and “functionality”. These are followed by “accessibility”, “aesthetics”, and “energy conservation”. According to the findings, QFD was shown to be an appropriate method for transferring customer (occupant) requirements to designs in the most accurate manner, given the complex structure of thermal hotel buildings.

In order to obtain high quantity and qualified animal foods, it is of great importance that the feeds used in feeding these animals have the necessary characteristics. For this reason, in this study, it is aimed to increase customer satisfaction by considering voice of customer in feed production and to produce solutions to problems and problems. In this study, Quality Function Deployment has been applied in order to improve the process and identify needs and complaints of animal breeding enterprises for a feed factory which is producing in Balıkesir province. Customers are the managers of livestock enterprises operating in the livestock sector in this province.The analyzes of the research were made on the data obtained between January and April 2019. The customer requests were analyzed on site by means of gemba analysis and the expectations were collected directly from the observations. Technical characteristics that can correspond to the demands were determined by calculating the importance levels of customer needs grouped as quality, price, packaging, distribution for feed production. After examining the relationship between customer needs and the technical characteristics that can meet them, determining the level of technical importance, and the competitive analysis stages, the quality house was created. While the most important criterion for the customer expectation part is "Delivery on Time", "Payment Type Price Discount" has received the highest value among the corresponding technical characteristics.
