Need and concept of software quality evaluation using artificial neural network (ANN) is described in the article. Architecture and structure of an artificial neural network of quality evaluation have been developed. The process of ANN training and testing was investigated. Research of ANN functioning results was conducted. ANN on the basis of design stage metrics analysis allows to make a comparative analysis of different projects and choose the best one of the characteristics of complexity and quality.

The aim is reducing IEC 61508 certification effort for safety-related applications. Therefore, an object-oriented middleware has been implemented which, once being SIL3-certified, would allow transferring safety-related aspects from the application into an already-certified code layer. Safety-related applications using this middleware then could be written as straightforward as non-safety-related code. The SIL3 middleware is designed for an 8051-based microcontroller. Because of the 8-bit CPU architecture, several limitations have been encountered. These issues are explained in this paper, and solutions are proposed. The middleware will be used on the multi-more safety chip. SIL3 certified multi-core architecture for safety-related applications is described. Also, the SIL3 middleware architecture is given. The middleware is modular. Therefore, if the user does not want to use some modules they will not be included and code footprint will be smaller. In the SIL3 middleware numerous design patterns can be found. Patterns description and purpose are explained. The pseudo code for the singleton pattern is shown. Moreover, module implementation is depicted. The validation of the middleware is presented and the V-model for the middleware is provided. It conforms to the IEC 61508.

In recent years, Pulse Transit Time (PTT) - based non-invasive continuous blood pressure monitoring systems have been investigated extensively. But the most relevant studies did not pay attention to the safety requirement of the system. In this paper a method is proposed to model the safety-related system for continuous noninvasive blood pressure monitoring. The V model, 1oo2 system and safe Bluetooth communication are used to enhance the safety of the system.

FPGAs introduce a very attractive platform for the designing process of complex embedded systems. The complexity of these systems should be controlled to fulfill high demands and requirements, especially in safety-related applications, where aspects like reliability, availability and safety are of the utmost significance. In this context, the present paper intends the design and implementation of a novel on-chip quadruple redundant safety-related system architecture (1oo4-architecture - one out of four) as a fault tolerant technique to increase the level of safety integrity, reliability and availability of electronic embedded systems. For this aim the 1oo4-architecture and their related safety characteristics are briefly demonstrated. The FPGA-based embedded system model of this novel architecture is developed and explained. The main part of this paper focuses on the safety-related implementation on FPGA. Finally, an evaluation of the implemented architecture concludes this paper.

In this paper, a concept for a SIL3 middleware implementing safety-related aspects is proposed. The middleware is intended to be used by applications that are written for a recently developed safety system-on-chip. Each module implements a low-level driver. Each driver represents a specific functionality of the system-on-chip. Once being certified conforming to IEC 61508, the middleware would enable writing safety-related applications aimed at SIL3 almost as straightforward as non-safety-related applications. A multi-core SIL3 architecture for safety-related applications is explained. In addition, possible issues that can arise during the software development are identified. Furthermore, conformance arguments on meeting SIL3 are depicted.

Recently, in Mathematical and Computational Applications Journal Chiu et al. [1] and Chen and Chiu [2] propose an inventory model based on EPQ with rework to determine the replenishment lot size and the number of shipments for a vendor-buyer integrated production-inventory system. They solve the inventory problem by considering both variables as continuous. However, the number of shipments must be considered as discrete variable. In this direction, this paper revisits and solves the inventory problem of [1-2] considering the decision variables according to their nature. Two easy and improved algorithms are proposed which simplify and complement the research works of [1-2].

In this paper, a new concept of bifuzzy bi-matrix game is introduced where all elements of the payoff matrices are characterized by bifuzzy variables. The uncertainties of entries of payoff matrices (bifuzzy variables) are measured by bifuzzy measure known as Chance measure. Combining the bifuzzy set theory and bi-matrix game theory, the solution concept of bifuzzy bi-matrix game theory is introduced. The quadratic programming problem plays the major role to solve bifuzzy bi-matrix game. In order to show the applicability and feasibility of our proposed method, a real-life bi-matrix game problem is considered and solved.

Using score function in a matrix game is very rare. In the proposed paper we have considered a matrix game with pay-off as triangular intuitionistic fuzzy number and a new ranking order has been proposed using value judgement index, available definitions and operations. A new concept of score function has been developed to defuzzify the pay-off matrix and solution of the matrix game has been obtained. A numerical example has been given in support of the proposed method.
