. The state and efficiency of production inventory management are the main conditions for the successful operation of an enterprise in a market economy. The main purpose of the enterprises' activities is to maximize profits, which can be achieved, inter alia, by increasing the turnover of stocks, when with a smaller warehouse area and lower inventory maintenance costs, the previous volume of sales increases or remains. The authors of the article analyzed modern methods of inventory analysis and management. Each of the considered methods has both advantages and disadvantages, so the use of a certain technique depends on the scope of the enterprise. Inventory management at the enterprise requires a rational inventory movement accounting system. The company should have a system for registering the acquisition and use of stocks. In addition, periodic checks of compliance with the actual availability of inventory and accounting data are required. Based on the conducted research, the main tasks in solving the problems of inventory management are identified: systematization of approaches to inventory management; reduction of costs for their acquisition and storage in warehouses of enterprises; increasing the efficiency of control in solving the tasks facing the enterprise. The existing structure of supplies of production stocks at railway transport enterprises does not allow for the full use of inventory management methods. In such conditions, it is necessary to create a managed system that will enable the use of various methods of management and optimization of production stocks. This system should include efficient logistics and management accounting of production stocks. It is advisable to introduce a system of standard (regulatory) costs in individual structural divisions. The use of combinations of methods for optimizing production stocks at railway transport enterprises will minimize operational costs through effective management of them.

Telepathology System

Abstract Background Telepathology is the practice of reviewing and exchanging pathological images through telecommunication systems to obtain diagnoses remotely. Studying the factors that make such a system successful and favourable is important to ensure the merits of its implementation in clinical practice. Objective This study aims to evaluate the success of a telepathology system from the users’ perspectives, using specific evaluation criteria, namely: system quality, information quality, technical service quality, user satisfaction, and benefits. Methods A sequential explanatory mixed methods design was adopted in this study, which consists of two phases. Initially, a questionnaire was distributed via WhatsApp to all of the pathologists (total: 45) working at governmental hospitals in Kuwait. Followed by, semi-structured interviews with ten senior pathologists. Results Forty pathologists responded to the questionnaire, giving an 89% response rate. There were 42.5% of the respondents aged between 35–44 years old, and 52.5% were male. The quantitative results reveal that most of the respondents were satisfied with the quality of the telepathology system with a mean of 2.6025 (Standard Deviation (SD) = 0.47176), whereas they were dissatisfied with the quality of the information with a mean of 2.4100 (SD = 1.580) and the technical support services with a mean of 2.2750 (SD = 0.99535). In addition, there was disagreement on the benefits of telepathology in clinical practice among the pathologists with a mean of 2.4667 (SD = 0.77552). The qualitative results indicate that the lack of interest in and little experience with using the system were behind the general dissatisfaction of most of the respondents. All of the interviewees were satisfied with the performance of the telepathology system and considered it successful; however, the quality of the technical support services, including training workshops, was deemed deficient. Conclusion This study concluded that telepathology system in Kuwait is functioning well and has been successful in its implementation; however, pathologists are dissatisfied with it, mainly due to the deficient quality of the technical support services provided. In addition, the successful implementation of such advanced technologies requires careful steps to be taken on multiple levels: technical, organisational, and managerial. Recommendations were suggested.

Because of the stochastic nature of production systems, it is necessary to first build an uncertainty model for subsequent real applications. Moreover, process parameter planning, quality design, and production inventory management are interdependent elements. In this research, a computer simulation model via computer-aided engineering (CAE) was developed to determine the optimal process parameters, lot size, and back order intervals for an integrated process design and inventory management system with simultaneous quality and cost considerations. Based on the estimated process time and costs obtained using CAE, the derived production rate and unit cost were then used for production inventory applications. In consideration of the uncertainty factor, the response surface method (RSM) was employed to analyze the output, namely the total costs incurred in employing the proposed approach, as well as the inputs, which include the cutting parameters, production quantity, and back order intervals. After the RSM was used to obtain the response functions, which represent the output of the collective interests, the mathematical programming (MP) was formulated based on the response functions to determine the optimal process parameters, process quality levels, production order quantities, and back order intervals. The total cost per set time unit was minimized by determining the required quality level, process parameter values, Economic Production Quantity (EPQ), and back order intervals. A cutting example was chosen to demonstrate the proposed approach. Two cases were used for comparison: the Integrated Case (the proposed approach herein) and the Disintegrated Case.
