Commercial aquaponics systems remain a challenge independent of the country, fish, plant species, or system design type. Most aquaponics systems are made by hobbyists, with aquaponics not being the main source of income. As such, scholars and practitioners have long debated the real profitability of aquaponics systems. With the growth of the aquaponics industry and commercial businesses, sustainable economic viability is necessary. Recently, considerable literature has been published around the theme of aquaponics systems design but there is a gap in the literature regarding the business aspect of this. Moreover, only by acquiring the enterprise knowledge of planning a business case, obtaining funds, and running and maintaining a business will this industry be able to grow. This paper intends to create a directory of possible considerations to plan for a viable commercial aquaponics system by uniting already established business frameworks and adapting them to the aquaponics industry. This framework proposes a guide to evaluate the economic feasibility of the enterprise depending on the revenues, costs and investments needed for the chosen system within its operations, market, and environment.

The contradictory integrity of the global and the local is viewed as a source of transnational and regional development. Design is an important aspect of glocalization, which ensures the “formulation” and introduction of basic ideas into the real life, and a space of compromise and interaction between the global and the local. It is clearly demonstrated by contemporary branding systems. Design as a scientific and educational space is presented in glocal discourses through the work of the Design Department of INRTU.

Study Questionnaire

Purpose: The purpose of this study is to reveal and examine the nature of costing systems design alongside the usage of new manufacturing practices in Jordanian Manufacturing Companies. Design/Methodology/Approach: For carrying out the study, 86 managers from 43 manufacturing companies received the study questionnaire from which 56 were valid for data analysis. The study results are presented using multiple regression analysis. Findings: The results using multiple regressions indicate that Just in Time (JIT), Total Quality Management (TQM) and Product Diversity (PD) has a significant influence on costing systems design. Implications: This study provides evidence on the importance of using management practices as a driver for companies to use a broader perspective for designing costing systems. Responding managers have now empirical evidence regarding the manufacturing practices needed to design costing systems to their companies. Originality/Value: This is the first attempt to examine the manufacturing practices as a driver for cost system design. The study also provides significant managerial implications on how to use manufacturing practices to ensure better cost system design.

Time Performance

Purpose The purpose of this paper is to propose a software engineering procedure for real-time software development and verification of an autonomous underwater robotic system. High performance and robust software are one of the requirements of autonomous systems design. A simple error in the software can easily lead to a catastrophic failure in a complex system. Then, a systematic procedure is presented for this purpose. Design/methodology/approach This paper utilizes software engineering tools and hardware-inthe-loop (HIL) simulations for real-time system design of an autonomous underwater robot. Findings In this paper, the architecture of the system is extracted. Then, using software engineering techniques a suitable structure for control software is presented. Considering the desirable targets of the robot, suitable algorithms and functions are developed. After the development stage, proving the real-time performance of the software is disclosed. Originality/value A suitable approach for analyzing the real-time performance is presented. This approach is implemented using HIL simulations. The developed structure is applicable to other autonomous systems.

Biased Information

During the early stage design of large-scale engineering systems, design teams are challenged to balance a complex set of considerations. The established structured approaches for optimizing complex system designs offer strategies for achieving optimal solutions, but in practice suboptimal system-level results are often reached due to factors such as satisficing, ill-defined problems, or other project constraints. Twelve subsystem and system-level practitioners at a large aerospace organization were interviewed to understand the ways in which they integrate subsystems in their own work. Responses showed subsystem team members often presented conservative, worst-case scenarios to other subsystems when negotiating a tradeoff as a way of hedging against their own future needs. This practice of biased information passing, referred to informally by the practitioners as adding “margins,” is modeled in this paper with a series of optimization simulations. Three “bias” conditions were tested: no bias, a constant bias, and a bias which decreases with time. Results from the simulations show that biased information passing negatively affects both the number of iterations needed and the Pareto optimality of system-level solutions. Results are also compared to the interview responses and highlight several themes with respect to complex system design practice.

Abstract This investigation focuses on the development of modifications to the Collaborative Optimization (CO) approach to multidisciplinary systems design, that will provide solution capabilities for multiobjective problems. The primary goal of this research is to provide a comprehensive overview and development of mathematically rigorous optimization strategies for MultiObjective Collaborative Optimization (MOCO). Collaborative Optimization strategies provide design optimization capabilities to discipline designers within a multidisciplinary design environment. To date these CO strategies have primarily been applied to system design problems which have a single objective function. Recent investigations involving multidisciplinary design simulators have reported success in applying CO to multiobjective system design problems. In this research three MultiObjective Collaborative Optimization (MOCO) strategies are developed, reviewed and implemented in a comparative study. The goal of this effort is to provide an in depth comparison of different MOCO strategies available to system designers. Each of the three strategies makes use of parameter sensitivities within multilevel solution strategies. In implementation studies, each of the three MOCO strategies is effective in solving two multiobjective multidisciplinary systems design problems. Results indicate that these MOCO strategies require an accurate estimation of parameter sensitivities for successful implementation. In each of the three MOCO strategies these parameter sensitivities are obtained using post-optimality analysis techniques.

In this chapter we examine systems that link People-to-People-to-geographical-Places, which we label P3-Systems. Four major P3-Systems design approaches have been identified by an analysis of systems prototyped to date: (1) People Centric P3-System design that use absolute user location, based on awareness of where somebody is located (e.g., Active Badge); (2) People Centric P3-System design based on user co-location/proximity (e.g., Hocman); (3) Place Centric P3-System design based on the use of virtual spaces that contain representations of user’s use of physical spaces (e.g., ActiveMap); and (4) Place Centric P3-System design based on the use of virtual spaces that contain online interactions related to physical location (e.g., Geonotes). This chapter explores how proximate community member interactions can potentially be well supported by P3-Systems through the improved geographical contextualization and coordination of interactions and the identification of previously unidentified location based affinities between community members.

Internal Benchmarking

The design and implementation of a globally integrated e-HRM system within a multinational corporation (MNC) requires different parties to reach some form of agreement on which HR processes must be standardised and which must be locally adapted. In this respect, the IT-based integration of HRM presents an intriguing setting in which to study micro-political behaviour during HRM integration, that is, how parties promote their own interests and the strategies they use during negotiations. Accordingly, the study’s aims were to identify those issues which generated the greatest degree of conflict during the IT-based integration of HRM, the key actors involved and the resources that were deployed during negotiations. A longitudinal, in-depth case study approach was used, and followed the integration of a global e-HRM system in the Finnish subsidiary of a large European-owned MNC over a period of nearly two years. Qualitative data was collected via semi-structured interviews with key subsidiary HR personnel and was complemented with company documentation. The findings indicate that the key areas of conflict were system design, the standardised use of English, and grey areas of HR policy. Three key parties were identified as being involved in subsequent negotiations. These parties utilised a range of negotiation resources including business case logic, technical know-how, internal benchmarking, local constraints and ignorance.
