Information Management Systems

It is agreed that good communication systems between organisations increase customer satisfaction and relationship behaviour and are important issues in chain collaboration and competition. However, less is known about the details of how information is used to manage relationships and coordinate customers and suppliers in chains. In earlier stages of the research, a dynamic model of interorganisational information management systems (IOIMS) and relationships was developed. This chapter presents an evaluation of this model based on a survey of Australian food processors and a green life industry case study and an evaluation of a revised version of this model. It was found that a strategic-oriented IOIMS were positively associated with IOIMS satisfaction that was, in turn, positively associated with perceived current outcomes (satisfaction with performance, perceived responsiveness, and strength of relationship trust). However, (attitudinal) commitment to develop long-term customer/supplier relationships was not significantly associated with the IOIMS, IOIMS satisfaction, or current outcomes. Results were moderated by the nature of the business environment—power/dependency, experience, and market uncertainty. These findings are discussed along with implications for management and suggestions for future research.

System Interfaces

Major factors affecting the reliability of railroad or transit systems are assigned at the design stage of a project. After the design of the system has been finalized changes that can be implemented to improve the reliability are generally of the second order level and subsequently have a lesser effect. An area that has traditionally been a source of unreliable operation for railroad and transit systems has been the interfaces between the various systems. The system-to-system interfaces cover the whole of the range of areas in a railroad or transit system and are often visible to the passengers using the railroad or transit system. The interfaces to be controlled have a wide variety of characteristics and features. These interfaces can consist of mechanical issues like for the platform and vehicle interface. The interfaces can also be mainly electrical in nature as with the control of conducted interference currents at the vehicle power supply interface to achieve compatibility. Interfaces may also be a mixture of mechanical and electrical characteristics. Railroad and transit systems are becoming more sophisticated, it is now common for a rail vehicle to have multiple microprocessors on board to control the various systems needed for a modern rail vehicle. Similar technologies are also being applied to different systems of a railroad or transit system. For example the technology required to control a vehicle propulsion system is very similar to that required by the modern regenerative substation. Modern integrated systems are also spreading across the traditional system boundaries. For example an integrated passenger information system for an LRT or Metro system would span vehicles, stations, train control and communication systems. A key factor to improving the reliability of a railroad or transit system is early and effective control of the system interfaces and having the appropriate organization(s) responsible for the interface. This paper will explore the factors that would need to be considered for appropriate management of the interfaces. It will relate the management of the interfaces to the types of contract mechanisms that can be used for procurement of equipment and consider the associated advantages and risks.

Factors Affecting Performance

Massive machine type communications (mMTC) are one of the critical requirements for beyond fifth generation (B5G) communication systems. Services for a huge number of user terminals should be provided simultaneously due to the explosive development of mMTC. It is proved that non-orthogonal multiple access (NOMA) is effective in satisfying such a requirement. In this paper we evaluate the impacts of numerous factors, such as channel encoding, channel decoding, repetition number, multi-user detector, and number of receiver antennas, on the performance of NOMA. It is surprised to find that some conclusions drawn from orthogonal multiple access system may do not hold anymore for NOMA systems. The factors which have significant impact on the performance of NOMA should be paid more attention to in the system design. The analysis and evaluation results shine more light on how to design an effect NOMA scheme by considering both transmitter and receiver to fulfill the requirements of mMTC for B5G systems.

Corporate Learning

The relevance of the study conducted in this article is due to the fact that the development of educational technologies in the digital economy will allow in the next 15 years to introduce accelerated methods in education, radically improving the learning of the material, and create communication systems “man - man”, “man - machine”, “man - society”. The purpose of this study is to identify and review the main factors affecting the transformation of the role of corporate training in the modern world, and key global trends in corporate training today. The objectives of the study were: search and creative development of information on the factors and trends of corporate training; prioritization and structured description of the identified factors and trends. The empirical base of the study was the materials of the European Foundation for Management Development (EFMD), the Association for the Development of Talent (ATD), and case studies of corporate universities. Practical significance consists in identifying the factors that influence and may affect the change in the corporate learning process and its global trends. This study allows one to form corporate training business models in the conditions of the digital economy development.
