Organisational resilience in a cloud-based enterprise in a supply chain: a challenge for innovative SMEs

The main idea of the paper is to analyse the organisational resilience potential of enterprises that may be modelled as a non-cloud enterprise or modelled from the perspective of being a cloud-based enterprise in a supply chain. In this manner, the model of an organisation is presented as a network of business processes. Organisational resilience factors (RFs) are assessed on the level of each business process and the overall level of organisational resilience potential is obtained for each organisation. The level of organisational resilience potential in these organisations is assessed when the enterprise is modelled, in the first place, as a non-cloud enterprise and also modelled from the perspective of being a cloud-based enterprise in a supply chain. In this way, the level of organisational resilience potential may be compared and analysed, which is a significant benchmark starting point for this research and practice domain.

Model for Selection of the Best Location Based on Fuzzy AHP and Hurwitz Methods

The problem of evaluation and selection of parking lots is a part of significant issues of public transport management in cities. As population expands as well as urban areas, solving the mentioned issues affects employees, security and safety of citizens, and quality of life in long-time period. The aim of this paper is to propose a multicriteria decision model which includes both quantitative and qualitative criteria, which may be of either benefit or cost type, to evaluate locations. The criteria values and the importance of criteria are either precise or linguistic expressions defined by trapezoidal fuzzy numbers. The human judgments of the relative importance of evaluation criteria and uncertain criteria values are often vague and cannot be expressed by exact precise values. The ranking of locations with respect to all criteria and their weights is performed for various degrees of pessimistic-optimistic index. The proposed model is tested through an illustrative example with real life data, where it shows the practical implications in public communal enterprises.

Resilience of Virtual and Networked Organizations: An Assessment

Virtual organizations (VO) represent a future paradigm of business. Having in mind different types of perturbations in business today, from the economic crisis to the earthquakes in Japan and terrorists’ actions, new business solutions have emerged in order to sustain development all over the world. As a new field in scientific research, organizational resilience needs to be investigated in the context of VOs. This paper has the intention to suggest a qualitative way to assess one dimension of organizational resilience in VOs and to establish directions for future work, emphasizing the importance of quantifying overall organizational resilience.

Supplier Selection using NSGA-II Technique

In modern manufacturing industries, supplier selection is increasingly recognized as a critical decision in supply chain management. Supplier selection problem is a typical multiple criteria decision making problem involving a number of different and usually conflicting objectives. Because of that, modern supplier selection techniques imply solving of multi-objective optimization problems. In this paper supplier selection using evolutionary algorithm (NSGA-II method) is presented. Recent investigations show that quality and costs are among the most important selection factors. In this paper the authors used variance of quality and total costs as criteria for selection optimization. Results show that described methodology can be applicable for the practical purposes.

Supplier Selection Using Multiobjective Evolutionary Algorithm

Supplier selection is one of the most critical activities of purchasing management. Nowadays, supplier selection includes a number of different and usually conflicting objectives. Because of that, modern supplier selection techniques imply solving of multiobjective optimization problems. In this paper supplier selection using evolutionary algorithm (SPEA method) is presented. As criteria for selection optimization we used variance of quality and total costs. Results show that described methodology can be applicable for the practical purposes.

Integration of Virtual and Networked Organization Using Server Oriented Architecture

Virtual enterprise integration (VEI) is virtually the most critical success factor for making virtual enterprise (VE) a real, competitive, and widely implemented organizational and management concept. One of the possible approaches in virtual enterprise integration is employment of web services. In this paper we will present an approach for developing an SOA for VEI. The general assumption of the suggested approach is that service oriented architecture is based on business services and they mostly correspond to exchanged documentation in a real business system. CASE tool for web service specification is also presented.
