The challenge of designing complex engineered systems with long service lives can be daunting. As customer needs change over time, such systems must evolve to meet these needs. This paper presents a method for evaluating the reconfigurability of systems to meet future needs. Specifically we show that excess capability is a key factor in evaluating the reconfigurability of a system to a particular need, and that the overall system reconfigurability is a function of the system’s reconfigurability to all future needs combined. There are many examples of complex engineered systems; for example, aircraft, ships, communication systems, spacecraft and automated assembly lines. These systems cost millions of dollars to design and millions to replicate. They often need to stay in service for a long time. However, this is often limited by an inability to adapt to meet future needs. Using an automated assembly line as an example, we show that system reconfigurability can be modeled as a function of usable excess capability.

Planning Approach

In der Produktion technischer Erzeugnisse sind Montageanlagen heute weit verbreitet. Durch immer kürzer werdende Produktlebenszyklen und die zunehmende Variantenvielfalt steigt auch die Zahl der durchzuführenden Anlagen(um)planungen. Vorgestellt wird ein Konzept, um automatisiert Entwürfe für Montageanlagen zu generieren. Auswahl und Anordnung der benötigten Betriebsmittel erfolgen dabei ausgehend von einem digitalen Modell des Produktes sowie einer Bibliothek verfügbarer Ressourcen. Die getroffenen Planungsentscheidungen werden simulativ abgesichert und heuristisch optimiert.   Nowadays, assembly lines are widely used for the production of goods. Due to shorter life cycles and increasing variance of products to be manufactured, assembly systems have to be (re)configured more frequently. This paper presents a concept to automatically generate drafts of complete assembly lines. Basis for the planning approach is a library of available resources and a digital product model. An algorithm selects, combines and arranges suitable resources. The planning decisions are heuristically optimized and verified by simulation.

Cobots and robots are integral to automated manufacturing operations. Although there are many studies in the field of industrial robots and cobots to make them safer the number of OSHA accidents due to cobots and robots has not decreased. Even though these cobots are considered inherently safe, they open more probability for accidents because they are not caged. Therefore, it is necessary for the manufacturing industries using cobots to consider the risk involved in human cobot interaction and the ways to attain safety and lower the risk of injury before installing cobots on assembly lines. A user-centric tool was developed to perform an ergonomic risk assessment using process- failure mode effect analysis for different automation levels in human-cobot interaction. The tool suggests recommended actions and various options to eliminate physical injuries. The results provide insights about safety analysis that can be used by manufacturers to improve safe human cobot interaction.

Definition Of

A well-presented business architecture will provide a holistic view of the enterprise. This will best enable management to see the critical structures and how they work together to determine what improvements can be made and what risks may exist. This chapter will show how the idea of architectural principles can be used to guide the development of an architectural reference model which can then be used by the planning staff to develop and present the organisational analysis in the form of architectural blueprint of the organisation. An architectural blueprint of the organisation would go a long way to ensuring that all the staff are on the same page by including the strategic plan and risk assessment plan within the business architecture; then it would ensure the development of the organisation would be as effective as possible. TOGAF provide a very detailed definition of ‘Enterprise Architecture' which covers all the topics from the Strategic Plan, Business Architecture to the IT System, but the TOGAF focus is very much on requirements to build the IT system. This book is aimed at the business manager developing the business architecture for organisational improvement, with IT there only as another value adding activity.

Residential Properties

Risk analysis of residential real estate investments requires careful analysis of certain variables (or determinants). Because real estate is a key sector for economic and social development, this risk analysis is seen as critical in supporting decision processes relating to buying or selling residential properties, partly due to the pressures caused by the current economic environment. This study aims to develop a conceptual reference model for risk assessment of residential real estate using fuzzy cognitive mapping. This fuzzy model allows cause-and-effect relationships between determinants to be identified and better understood, which in turn allows for better informed investment decisions. The results show that the use of cognitive maps reduces the number of omitted criteria and favors learning with regard to how the criteria relate to each other, holding great potential and versatility in structuring complex decision problems. Practical implications, strengths and weaknesses of our proposal are discussed.
