Supplier selection for defence procurement is a crucial function of a Ministry of Defence. The Ministry spends huge amounts of money each year to procure a vast array of equipment, goods and services. The ongoing financial crisis demands less subjective and more cost-saving methods for selecting a supplier. The approach advocated in this article integrates Analytic Hierarchy Process (AHP) with Goal Programming (GP) in order to combine conflicting criteria to select the best suppliers and allocate optimum order quantities among them. This paper presents a model close to real-world situations. Findings demonstrate that cost savings is a feasible result along with a viable combination of conflicting criteria in the suppliers' selection area.

This article reports on the influence of the enterprise type on the purchasing decision process within selected product types and phases by using analysis of variance on data from Greek manufacturing and utility enterprises. Our study examined the influence of enterprise type on four parameters of the purchasing decision process, across two different product types and four phases of the purchasing process. The results suggested that all but one parameter varied considerably among the different types of enterprises, and that companies adopt an appropriate structural configuration, which fits to the attributes of the purchased items and the mission of the enterprises.

The purpose of this research is to investigate the extent of outsourcing, the decision‐making process, the impact of outsourcing, and the future trend of outsourcing in public hospitals in Greece.

A survey instrument was designed and mailed to a random sample of 100 public hospitals in Greece and 43 usable questionnaires were received, representing a response rate of 43 percent. The survey instrument focused on the extent to which public hospitals outsource services, the decision‐making process for choosing an external service provider, the impact of outsourcing, and the future trend of outsourcing in public healthcare organisations.

Public hospitals in Greece outsource a variety of activities. Cost savings and customer satisfaction are the main factors affecting the outsourcing decision. The cooperation with a contract service provider has led to significant improvement in service quality levels. Most users are satisfied with the performance of these companies and believe that there will be an increase in the usage of these services in the future.

It provides a decision‐making framework regarding outsourcing in public healthcare organisations.

This research fills the gap in the area of outsourcing in public hospitals in Greece.

The purpose of this paper is to present a study carried out to investigate the extent of outsourcing, the decision‐making process, the impact of outsourcing, and the future trend of outsourcing in private healthcare organisations in Greece.

A survey instrument was designed and mailed to a random sample of 100 private healthcare organisations in Greece. A total of 25 usable questionnaires were received, representing a response rate of 25 percent. The survey instrument focused on the extent to which private healthcare organisations outsource services, the decision‐making process for choosing an external service provider, the impact of outsourcing, and the future trend of outsourcing.

Private healthcare organisations in Greece outsource a variety of activities. Cost savings, customisation, and customer satisfaction are the main factors affecting the outsourcing decision. The cooperation with a contract service provider has led to an improvement in customer satisfaction and to a cost reduction. Most users are highly satisfied with the performance of these companies and believe that there will be a future increase in the usage of these services.

The paper provides a framework regarding outsourcing in private healthcare organisations.

The purpose of this paper is to seek to contribute to the assessment of the impact of a number of decision-making criteria in resolving tactical make-or-buy issues in enterprises operating in Greece. Moreover, it sheds light on the relationship between the impact of each criterion and a number of independent variables.

Initially, depth interviews were made with purchasing managers in ten industrial firms operating in Greece. The findings of these interviews and the review of the pertinent literature provided the basis for the questionnaire design. Then, a copy of the questionnaire and a prepaid self-addressed return envelope were mailed to a stratified sample of 300 industrial firms operating in Greece. By the end of this process, 85 questionnaires were received, representing a 28.3 percent response rate.

Cost and quality appear to be the criteria with the most impact, which indicates that companies usually resolve tactical make-or-buy issues in order to achieve short-term cost savings or operational advantage. The emphasis placed upon the other criteria tends to vary with the situation under which the particular make-or-buy issue is resolved.

It develops a more precise assessment of the impact of each make-or-buy decision-making criterion and investigates the relationship between this impact and a number of independent variables.

This article reports on the influence of product type on the purchasing structure within selected phases of the purchasing process by using regression analysis on data from Greek manufacturing and utility enterprises. Our study examined the influence of two different categories of items, namely product incorporated items and MRO (maintenance, repair and operating) items, on various aspects of the purchasing cycle. The results suggested that parameters of purchasing structure varied considerably between the two product types and that their configuration depended on attributes such as product complexity and environmental uncertainty.

This paper aims to provide a strategic approach to the improvement of customer service performance and apply it to a food supplier that distributes its products to food multiple retailers' stores (from now on, the term “retailers” instead of “food multiple retailers' stores” will be used to represent hypermarkets, supermarkets or neighbourhood stores).

To attain the performance's enhancement, the requirements are: the identification, evaluation and selection of customer service elements and the establishment of measures as well as performance standards. To identify service elements, previous research and the food supplier's as well as the retailers' viewpoints were taken into consideration. To evaluate service elements, 40 retailers were asked to rate the elements' importance and the two competitors' performance. The usable questionnaires were subjected to correlation analysis, paired‐samples t‐test and multiple ANOVA. To select the appropriate service elements, on which measures and performance standards would be established, positioning matrices were also formed.

With respect to sausage market in Greece, the analysis points out that the supplier should apply measures in the service elements order completeness, invoice error‐free, on‐time delivery, delivery of products without defects, efficient handling of returned products, informing about shortages in the orders, providing technical information and efficient handling of customers' requests. The performance should be improved in the first three elements and maintained as it is in the remaining five elements.

The study provides insight into the customer service elements which a supplier should measure and into which of them a supplier should improve its performance or maintain it. Moreover, the elements that constitute customer service in the Greek sausage sector are identified.

This paper aims to find the best tools to influence the improvement of sustainability in food supply chains (FSCs) by conducting a systematic review of articles. The reader will learn how the different industry 4.0 tools (I4.0T) benefit the FSC and the limitations of each tool.

A review of 436 articles published during the period 2019 to 2022 referenced in the Scopus and Web of Science databases was performed. The review was limited to articles published in English and directly related to Industry 4.0, circular economy and sustainability in the food supply chain.

The results show different contributions of I4.0, with some being more influential than others in improving sustainability in FSCs; for example, Internet of Things and Blockchain have been shown to contribute more toward transparency, traceability, process optimization and waste reduction.

The paper's contribution consisted of ranking according to their importance and the I4.0T that affect sustainability in FSCs by classifying the aspects of each tool and the sustainability factors through a categorization by the Analysis Hierarchy Process.
