Digitalisierungsprojekte sind Softwareprojekte. Sequenzielle Planungsmethoden, wie sie im konventionellen Projektmanagement überwiegend Anwendung finden, eignen sich nur bedingt für diesen Projekttyp, da die anwendungsspezifischen Anforderungen sowie die Abhängigkeiten der Anlagen und IT-Systeme untereinander zu einem erheblichen Anstieg der Gesamtkomplexität führen. In diesem Beitrag wird daher ein Ansatz zur systematischen Auswahl geeigneter Projektmanagementmethoden für Digitalisierungsprojekte vorgestellt, welcher die traditionelle Projektplanung im Produktionsumfeld um iterative Vorgehensweisen aus der Software- entwicklung ergänzt.   Digitalization projects are software projects. Less suitable for such projects are sequential planning methods often used in conventional project management, as application-specific requirements and interdependencies of facilities and IT systems considerably increase overall complexity. Therefore, this paper presents an approach for the systematic selection of suitable management methods for digitalization projects, which adds iterative procedures from software development to traditional project planning in the production environment.

This paper focuses on the use of Fuzzy Analytic Hierarchy Process (FAHP) and VlseKriterijumska Optimizacija I Kompromisno Resenje in Serbian (VIKOR) to select an optimum maintenance strategy for a textile industry. In the proposed methodology, first the weight of each criterion is calculated by using improved AHP with fuzzy set theory to overcome the problems of unbalanced scale of judgments, uncertainty and imprecision in the pair-wise comparison process and then the VIKOR method is applied to compensate the imprecise ranking of the AHP in the selection of maintenance strategy. The real case study is conducted for a textile industry to illustrate the utilization of the proposed model for the maintenance strategy selection problem. Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is applied to make sure that the result of the proposed model can be acceptable. A sensitivity analysis is also conducted to show the validity of the proposed model. The paper gives an insight into multi criteria decision-making (MCDM) techniques to select an optimum maintenance strategy for a process industry using a case study.

In the selection of an economical treatment for rehabilitation of a deteriorated pavement section, decision makers usually encounter various situations. Factors affecting selection of a flexible pavement maintenance strategy may include distress conditions, traffic volume, and road class, among others. Traditionally engineers make their selection on the basis of their experience and judgment and past maintenance data. Experts’ judgments are usually compromised in a group discussion to construct decision trees or decision matrices or even to develop knowledge-based expert systems. An artificial neural network is known to be an efficient technique for selection of an appropriate maintenance strategy. A genetic adaptive neural network training algorithm with a single hidden layer and sigmoid squashing function constitutes the network. The input vector represents the factors affecting maintenance strategy selection, and the output vector represents the appropriate maintenance strategy. A set of examples is derived from experts’ judgments with a total of 144 cases randomly divided into “in-sample” and “out-of-sample” data for training and testing purposes, respectively. The trained network successfully predicted 83 percent of the test cases. The remaining 17 percent of cases were one or two levels away from the expert judgments used in network testing. Neural networks provide an efficient and optimum solution for such complex problems with the added advantage of faster implementation and easier updating than with other traditional techniques.

Advanced computer systems played an important role in economic life for a long time. We can notice it in all aspects of business operations, including logistics. IT systems are important not only in the logistics activities of individual operators, but they also improve activities within integrated supply chains. The article focuses on the proper selection of IT system for logistics operations. It presents a comparison of selected IT systems dedicated to logistics: their range of functionalities and features, as well as the ability to use it in specific types of enterprises. The main aim of the article is to analyze the suitability of each ERP systems in two main areas of logistics: storage and transport. The author also attempts to select optimal solution for a particular economic operator.

An optimal maintenance strategy is a key support to production in the manufacturing industry. This paper present a fuzzy approach based on Multi-Criteria Decision-Making (MCDM) methodology for selecting the optimal maintenance alternative. In the present work the criticality of each equipment is achieved by ranking (based on production loss).It is very difficult to quantify the qualitative factors in exact numerical value. These factors can be expressed in the linguistics terms which can be translated into mathematical measures by using fuzzy sets & system theory. The study problem to develop a fuzzy decision approach to rank the suitable maintenance alternative. The objective of this paper is to propose fuzzy frame work based on fuzzy number theory to solve optimal maintenance alternative which includes decision criteria analysis, weight assessment & decision model development. The approach can aid formulating a cost-effective maintenance strategy for a manufacturing plant.
