Risk scoring methods applied in risk assessments used in Turkey, differ from each other in terms of analysis methods, scoring the risks, presumption and sensitivity levels. This article aims to eliminate the effects of divergent results of different risk analyses of lifting equipments used in the building industry and develop a practical hybrid risk analysis and ranking method. In this study risks of lifting equipments used in the building industry were scored by conventional Fine-Kenney risk analysis method first. Secondly, with the experience of previous accidents on construction sites, the reasons of accidents were sorted into 7 main criteria, which being ‘Demographic’, ‘Behavioral’, ‘Machine Related’, ‘Working Environment Related’, ‘Economical’, ‘Administrative’ and ‘Organizational’ criteria and related sub-criteria. Developing these criteria was supported by the experience of inspections carried out by labour inspectors. The weighted scores of these criteria were calculated by AHP method using a questionnaire applied to 14 experienced labor inspectors. The weighted scores obtained by the analytical hierarchy process method (AHP) were multiplied by the scores obtained by Fine-Kinney risk assessment method and a new integrated risk assessment and ranking application was introduced. With this application, a different priority rank was created and which risk to be eliminated primarily was determined. Keywords: analytical hierarchy process, lifting equipments, fine-kinney, occupational health and safety, integrated risk analysis, ranking method

The main focus of this paper is to propose a method for prioritizing knowledge and technology factor of firms towards sustainable competitive advantage. The data has been gathered and analyzed from two high tech start-ups in which technology and knowledge play major role in company’s success. The analytical hierarchy model (AHP) is used to determine competitive priorities of the firms. Then knowledge and technology part of sense and respond questionnaire is used to calculate the variability coefficient i.e. the uncertainty caused by technology and knowledge factor. The proposed model is tested in terms of two start-ups. Based on the initial calculation of uncertainties, some improvement plan is proposed and the method is applied again to see if the uncertainty of knowledge and technology decreases. In both cases, the proposed model helped to have a clear and precise improvement plan and led in reduction of uncertainty.

Site selection is one of the basic vital decisions in the start-up process, expansion or relocation of businesses of all kinds. Construction of a new industrial system in the form of solar photovoltaic power plant is a major long-term investment, and in this sense determining the location is critical point on the road to success or failure of industrial system. One of the main objectives in industrial site selection is finding the most appropriate site with desired conditions defined by the selection criteria. This work suggests how to define and classify particular criteria considered for solar PV farm siting. Multi-criteria decision analysis (MCDA) is proposed as a method to process available technical information to support decisions in many fields, especially in environmental decision making. In some cases, due to the lack of reliable information on the impact of various natural factors on the economic activity related to the use of land resources, the method of expert assessments can be used. The peculiarity of this method is the lack of empirical evidence of the influence of a given factor on the final result of decision-making. In this case the value of separate factor is judged by experts. When applying this method, expert groups are formed of leading specialists, the main influence factors is established, a questionnaire and a scale of criteria are compiled. Level of reliability of the results is assessed by the coefficient of concordance.

Content available remote Determination of Priorities in Apparel Purchasing from Private Sale Websites
EN
In the fast-changing internet era, private sale websites attracted an enormous interest from the consumers in especially online marketing of apparel goods. The retailers may garner more benefit if the prior issues for the consumers when they are purchasing apparel products online is known. Reviewing the literature, this study presents the factors in three groups in a hierarchical manner considering the multidimensional aspect of online purchasing of apparel products from private sale websites and then determines the prior issues for the consumers by making pairwise comparisons among these factors using analytical hierarchy process on a sample group of 100 Turkish respondents. The findings revealed that “privacy/security” in terms of online shopping criteria, “product information” in terms of apparel products criteria, and “discount ratio” in terms of private shopping criteria took highest scores of importance when the aspects were analyzed individually. Nonetheless, the parameters regarding the online shopping criteria were found to be more important than the criteria regarding the apparel products and private shopping criteria. In the end, it was also observed that these items that were found to have highest importance were actually corresponding to the risks of the situation.

This paper presents a model for selecting Architect/Engineer (A/E) professionals for construction projects. The model takes into account all relevant criteria considered by the owner. These criteria were identified through a comprehensive literature review, and were then clustered into seven groups, namely firm background; past experience; technical resources; management capabilities; financial stability; quality assurance; and innovation capability. The Analytic Hierarchy Process (AHP) was utilized to develop a model for A/E professional selection. This involved constructing a hierarchy of the decision, taking into account all of the identified criteria and sub-criteria and comparing the relative importance of each criterion with all other criteria. A synthesis of the results was undertaken to determine the ranking of the different professionals considered in the model. The paper is practically useful to owners interested in achieving the desired cost, quality and time in their projects.

The paper is to present a multi-criteria approach for sustainability assessment of manufacturing processes, which can be applied to carry out the sustainability assessment of manufacturing processes requiring less detailed data, time, and expert knowledge, but still providing a company-level analysis. The analytical hierarchy process method is used to determine ranking of simple and relevant activity areas for manufacturing processes in terms of sustainability objectives. Analytical technique is also employed to assess the degree of sustainability in manufacturing due to limited information which appear to be a characteristic of the case study presented. One goal of sustainability characterization methodology is to improve the manufacturing sustainability performance. Similar to the baseline scenario, sustainability reevaluation for sustainability improvement is also applied and discuses performance profile at the process level. This approach seems particularly useful when comparing different processes. It makes applicable for various industries and might be a challenge to derive priorities for systematic improvement. The applicability and usability of the proposed assessment method was verified by the case study in company producing heating devices.

In most cases, customers evaluate a product based on the first impression, which is propagated by the product itself. These impressions are often subjectively engraved in the products, difficult to describe thus making them difficult to handle. Technical specifications on the other hand are less considered at first sight. In the case of leisure products such as Motorbikes (motorcycles), subjective factors are considerably intensified. Thus, such products are suitable to describe as “difficult-to-quantify” characteristics. Subjective and difficult to quantify features for products such as motorcycles could be; the design, the dynamics (vitality) as well as the price (value) impression. Thus, amid a DFG research project, a method will have to be developed that allows the scaling of difficult to quantify characteristics in other to support a requirement-orientated product development. For this purpose, four different levels were developed to contain scaling based on usage. To support the scaling development, methods such as the AHP or the Multivariate Analysis Method can be used. In the following analysis it will be shown how perception-defining characteristics for motorcycles can be derived from design analyses. The first step is the design analyses conducted with the help of the analytic hierarchy process (AHP) scale based on Thomas L. Saaty. The advantage of this approach is a direct comparison of all alternatives to themselves. If, for example, five motorcycles are compared with regards to design, then a benchmark for good design implicitly arises. These scales build up dynamically depending on the analyzed alternatives. Based on the previous example, the more alternatives are used the more valid the scale. The systematic arrangement of the perception-defining characteristics in product development can be a deciding factor for a better product design and its related product perception. Special gender specific perception differences for motorcycles will be evaluated in this paper. Thus, it is shown that there are specific motorcycle models that appeal to women while other specific models are preferred by men. In this case, perception-defining characteristics can be derived from a detail analysis of a preliminary assessment which can aid the description of female and male preferences for motorcycles. In this paper a method to concatenate the perception-defining characteristics and products will be presented. Above all, these characteristics should be considered in the product planning phase. This approach offers producers the possibility, through identification of important perception-defining characteristics, to differentiate themselves from competitors because important product characteristics are deigned to relate to the various target groups.

The mass-customization trend as flexible production philosophy has been adopted by many industries as a reaction to the fast changing customer demand environment. In relation to that mixed-model production (MMP) is a possibility for increasing flexibility, especially in the assembly department. However, many apparel companies have failed in their transition from traditional manufacturing to new, flexible manufacturing, which makes it difficult for them to be selected as suppliers who are capable of MMP. In most of the studies that have been done before, the problem of supplier selection was based on productivity and cost as the main selection criteria. As an alternative solution this research presents a new group of criteria for supplier selection with respect to the goal of MMP. The methodology of combining the analytical hierarchy process (AHP) with the support of the commercial software package Expert Choice and cluster analysis (CA) is proposed in this study. The results obtained present a new group of criteria, ranked by their importance, that the supplier needs to fulfil in order to be selected for MMP. Furthermore the large number of available suppliers was grouped into four clusters based on their similar characteristics by using CA. Finally the most acceptable cluster for MMP was selected using AHP. The methodology presented in this study can support the apparel industry in better decision making in the process of selecting the best group of suppliers for mixed-model production.

Numerous countries are trying to find the best method for suitable management of real estate objects that encompass both material value and cultural property. Cultural property can be defined as historical heritage in the form of volumetric and planned spaces of buildings. Yet another problem lurks in utilization and maintenance of such buildings, which are usually regulated by national legislation thus aggravating certain decision-making processes related to their adjustment to the needs of the public or investors. This article addresses the status of some buildings located in the historic city centre of Vilnius and analyses indicators, on the basis of which such buildings could be assessed in order to identify their need for reconstruction, considering archaeological, historical, architectural, economic, social and other arguments. As experience in reconstruction suggests, such decisions demand for well-reasoned and precise concepts as each hasty conclusion usually results in mistakes that demand for additional work and funds. AHP and ARAS methods, which are well-known in decision-making, have been chosen to design the algorithm for priority setting.
