Abstract
This study proposes targeted modernization of the Department of Defense (DoD's) Joint Forces Ammunition Logistics information system by implementing the optimized innovative information technology open architecture design and integrating Radio Frequency Identification Device data technologies and real-time optimization and control mechanisms as the critical technology components of the solution. The innovative information technology, which pursues the focused logistics, will be deployed in 36 months at the estimated cost of $568 million in constant dollars. We estimate that the Systems, Applications, Products (SAP)-based enterprise integration solution that the Army currently pursues will cost another $1.5 billion through the year 2014; however, it is unlikely to deliver the intended technical capabilities.

Abstract
Purpose
The purpose of this paper is to explore the ways in which notions of space, constituted by management accounting and operations, interact, conflict and are understood by operations managers in a variety of situations within the context of iron ore mining. The authors address a dual question: How do accounting space and production space relate to each other? And what does it mean for operations managers to reside in both those spaces at once?
Design/methodology/approach
The paper is based on field studies at a mining company involving operations managers who experience tensions between accounting and production responsibilities and must prioritize between different courses of action to create value.
Findings
In contrast to the view that management accounting poses a problem for operations managers in production environments, the authors show how especially discursive tensions foster reflection and choice. Operations managers prioritize their actions in accordance with management accounting or operations based on how they experience and reflect upon the tensions they encounter, dominating artifacts and their experienced relation to space. Operations managers are not tied to specific spaces, but they prioritize their responsibility to management accounting or operations depending on the space to which they feel a sense of belongingness.
Originality/value
Drawing upon a conceptualization of tensions between management accounting and operations as a spatial phenomenon, it is possible to understand the dilemmas experienced by operations managers in a dynamic and relational way. The authors propose that viewing tensions between management accounting and production as spatial phenomena enables a novel understanding of how such tensions can create reflexivity in responsibility with operations managers.

Abstract
Overview All organisations are, in one sense or another, involved in operations; an activity implying transformation or transfer. The major portion of the body of knowledge concerning operations relates to production in manufacturing industry but, increasingly, similar problems are to be found confronting managers in service industry. It is only in the last decade or so that new technology, involving, in particular, the computer, has encouraged an integrated view to be taken of the total business. This has led to greater recognition being given to the strategic potential of the operations function. In order to provide greater insight into operations a number of classifications have been proposed. One of these, which places operations into categories termed factory, job shop, mass service and professional service, is examined. The elements of operations management are introduced under the headings of product, plant, process, procedures and people.

Abstract
Purpose
The purpose is to provide an intellectual history of Operations Management, particularly noting recent developments and its underlying continuity with earlier systems and thinking. Operations Management as a discipline identifies its “modern” incarnation as dating from the 1960s when it became more rigorous and managerially focused. This re-invention constructed a “narrative” that the profession still follows, yet a critical perspective reveals significant, though under-appreciated continuity with earlier theory and practice.
Design/methodology/approach
This paper presents a comprehensive literature review and comparative analysis of historic developments in management and academia.
Findings
In the early 1900s, F. W. Taylor’s Shop Management established Operation Management, but its main component, Scientific Management, had stagnated by the 1950s. At that point, the rise of Management Science both reinvigorated Operations Management and threatened it with a competing new discipline. To compete Operations Management then modernized by redefining itself, reasserting its interest in several areas and co-opting Operational Research tools for those. It also contracted, withdrawing from areas considered vocational, or more suited to Industrial Engineering.
Research limitations/implications
This historical overview shows the critical importance of drawing research agenda from practical managerial concerns.
Practical implications
Practitioners benefit from the intellectual rigor that academics provide and a historical perspective shows that the relationship has been mutually beneficial.
Social implications
The disciplines of Operations Management, Operations Research and Industrial Engineering are complementary and competitive in addressing many problems that transcend their boundaries, and use common ideas and techniques. The demands of “academic rigor” have had a deleterious effect on the practical managerial relevance of these disciplines.
Originality/value
A long-term, cross-disciplinary perspective provides a unique understanding of the research interests and practical orientations of these disciplines.

Abstract
Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

Abstract
In this chapter, we have presented four case studies of the firms which are operating in the medium complete adapting countries. The four cases are Arvidsson Textile Share Company in Estonia, Partec Rockwool in Lithuania, Accel Share Company in Lithuania and Ragn-Sells in Estonia. The case studies are prepared following the structure of the theoretical framework applied in this book. We have found out that the performance of Arvidsson Textile Share Company is successful as it matches the expectations if the partners and it has remained to be more or less the same since its establishment. The performance of Partec Rockwool was also successful from the very beginning until it was replaced by the fully owned firm. Accel Share Company's operations in Lithuania was successful from the very beginning as it found the right people with the right competence in the local market. In the case of Ragn-Sells in Estonia, the alliance was successful but not up to the full expectation.

Abstract
Purpose
The purpose of this paper is to investigate the relations in the Marketing/Operations interface through the analysis of data of the operational reality of a Brazilian company with a low technological intensity. The study aims to quantify and determine the impacts of marketing decisions on delivery performance and on flexibility of the operations area.
Design/methodology/approach
A longitudinal case study was conducted and the variables used in the model were derived from established theories and were evaluated with artificial neural networks. The case of a food manufacturing company was selected to reflect the relations in the marketing/operations interface of a low technological intensity enterprise.
Findings
The results show that the decisions on Place/Channel, Price and Product dimensions of marketing exert a significant impact on flexibility and delivery performance of the operation area.
Research limitations/implications
The findings of the case study cannot be generalised and the outcomes are specific to just one firm. However, the approach lends itself to replication, particularly within low technological intensity companies.
Originality/value
Prior studies have focussed on coordination among functional areas as marketing and operations at higher levels of abstraction. The study contemplate empirical propositions through the data analysis of a company with a low technological intensity that can be used to improve managers' decisions and alignment in the Marketing/Operation Interface.

Abstract
Contemporary literature reveals that, to date, the poultry livestock sector has not received sufficient research attention. This particular industry suffers from unstructured supply chain practices, lack of awareness of the implications of the sustainability concept and failure to recycle poultry wastes. The current research thus attempts to develop an integrated supply chain model in the context of poultry industry in Bangladesh. The study considers both sustainability and supply chain issues in order to incorporate them in the poultry supply chain. By placing the forward and reverse supply chains in a single framework, existing problems can be resolved to gain economic, social and environmental benefits, which will be more sustainable than the present practices.
The theoretical underpinning of this research is ‘sustainability’ and the ‘supply chain processes’ in order to examine possible improvements in the poultry production process along with waste management. The research adopts the positivist paradigm and ‘design science’ methods with the support of system dynamics (SD) and the case study methods. Initially, a mental model is developed followed by the causal loop diagram based on in-depth interviews, focus group discussions and observation techniques. The causal model helps to understand the linkages between the associated variables for each issue. Finally, the causal loop diagram is transformed into a stock and flow (quantitative) model, which is a prerequisite for SD-based simulation modelling. A decision support system (DSS) is then developed to analyse the complex decision-making process along the supply chains.
The findings reveal that integration of the supply chain can bring economic, social and environmental sustainability along with a structured production process. It is also observed that the poultry industry can apply the model outcomes in the real-life practices with minor adjustments. This present research has both theoretical and practical implications. The proposed model’s unique characteristics in mitigating the existing problems are supported by the sustainability and supply chain theories. As for practical implications, the poultry industry in Bangladesh can follow the proposed supply chain structure (as par the research model) and test various policies via simulation prior to its application. Positive outcomes of the simulation study may provide enough confidence to implement the desired changes within the industry and their supply chain networks.

Abstract
Purpose
The purpose of this study is to compare different models integrating the TOC and Lean approaches.
Design/methodology/approach
The models of reference were identified through a comprehensive literature review. A qualitative and comparative analysis was carried out by pointing out the strengths, weaknesses and gaps of models integrating the TOC and Lean based on the production system requirements.
Findings
The findings indicate that these models can be improved by introducing aspects related to the system structure such as main key performance indicators, type of shop layout and performance metrics to evaluate the improvements implemented in the production system. The results provided evidence that the TOC and Lean are complementary approaches, and the individual gaps of each approach seem to be, in the most part, offset by the virtues of the other.
Practical implications
This study enables decision makers and industrial managers to evaluate the practices adopted in the production environment, as well as the use of the different set of continuous improvement practices. This article also minimizes the literature gap regarding whether and how integrated Lean and TOC approach can be used in the firms.
Originality/value
This study contributes to the body of literature on Lean by comparing three different models integrating Lean and the TOC. Furthermore, a research agenda is suggested for future research aimed at developing new models integrating both approaches, aiming to increase the competitiveness of the production systems.
