In this study, an attempt is made to explore how individual systems thinking ability impacts on the supply chain.

The authors used a range of different research methods including surveys, tests, and simulations.

The results showed that individual systems thinking ability greatly influences the practice of supply chain management.

This study suggests that the rationality of managers in the decision‐making process is good – for the supply chain. To improve the supply chain efficiency with a more realistic solution, inventory and production managers have to make decisions with the systems' thinking ability and the consistency.

Aims to discuss the basic strategy taken by a specific manufacturer. States supply chain structures influence, directly, the supply chain inventory as a measure of performance. Examines the difference in the supply chain in relation to the manufacturer’s strategy to the product.

The purpose of this paper is to investigate the interactive effect of collective personality fit and its diversity on relationship conflict in a team context.

Data were collected from 1,265 employees and their leaders in 110 work teams in a Korean manufacturing company.

The results show that the two-way interaction between collective personality fit and its dispersion affects relationship conflict in teams. The effect of collective fit on relationship conflict was found to be weaker when the dispersion of collective fit is low than when it is high. This study reports that a high level of collective fit dispersion may help resolve relationship conflict in certain conditions, such as when the level of collective fit is high.

This paper implies that the diverse perception of fit does not always hamper intragroup consonance, and relationship conflict can be reduced as long as the overall level of collective fit is high. The diverse or heterogeneous personalities of team members contribute unique attributes of each member to the success of the team because some members of a heterogeneous team may play the role of filling the gap left by others.

This study argues that collective fit is a new construct, not a simple aggregation of individual fit traits, and the pattern of relationships at the individual level is not replicated at the group level, either conceptually or empirically.

The weapon system of The Navy is the small quantity producing system on multiple kinds. It is consisted of various equipment and the subordinate parts of those which can repair the damaged part. The operating procedure concerning warship's repair parts managed under these systems is as follows. Firstly, if demand of repair parts occurs from warship which is the operating unit of weapon, then the Fleet(the repair & supply support battalion) is in charge of dealing with these requests. If certain request from warship is beyond the battalion's capability, it is delivered directly to the Logistic Command. In short, the repair and supply support system of repair parts can be described as the multi-level support system. The various theoretical researches on inventory management of Navy's repair parts and simulation study that reflects reality in detail have been carried out simultaneously. However, the majority of existing research has been conducted on aircraft and tank's repairable items, in that, the studies is woefully deficient in the area concerning Navy's inventory management. For that reason, this paper firstly constructs the model of consumable items that is frequently damaged reflecting characteristics of navy's repair parts inventory management using ARENA simulation. After that, this paper is trying to propose methodology to analyze optimal inventory level of each supply unit through OptQuest, the optimization program of ARENA simulation.

The main streams of the supply chain are defined as material, information and financial flow. There have been many studies and practical cases regarding the flow of material and information including information sharing. However, financial flow related studies have not been widely examined relatively, compared with their importance.

The information sharing is recognized as the method that can reduce the Bullwhip effect in supply chain management. The author intends to analyze the impact of financial information sharing on the results of the supply chain.

In the point of supply chain risk management view, the author examined the impact of financial flow among the various factors that can impede the stability of the supply chain.

In this study, the author embodied the simulation regarding the impact of financial information flow on supply chain performance and stability based on the system dynamics methodology and analyzed the performance.

Assuming the supply chain, composed of supplying company, manufacturing company and sales company , the author embodied the simulation model and assumed that working capital and cash information sharing were achieved. The author embodied the model to affect the settlement conditions according to the results of financial information sharing.

The purpose of this paper is to examine the process of information communication technology (ICT) reform in a government school in Singapore. The focus is on the distributed leadership actions performed by various individuals, and how the multiple leaders and their leadership practices interacted with one another.

A naturalistic inquiry approach was adopted, involving the case study of a school in the process of implementing an instructional reform involving the use of ICT.

It was found that distributed leadership for ICT implementation requires a combination of transformational leadership and instructional leadership to develop teachers’ capacity to enhance their instruction with ICT, emotional leadership to support teachers’ effort to change, and strategic management of resources to sustain teachers’ change efforts. Transformational leadership is performed mainly by senior management (SM). Instructional leadership is performed mainly by middle management (MM). Both senior and middle management provided emotional leadership and strategic resource management. In addition, SM provided second‐order changes leadership, while MM provided first‐order changes leadership.

The paper rectifies the current disproportionate focus on the role of the Principal by uncovering the leadership actions performed by other school members, and how these leadership actions are interrelated. In particular, the paper provides insight into how leadership was distributed in a school reform involving the use of ICT for instruction.

Natural gas makes up about 50 per cent of Pakistan's energy consumption, which is decreasing at an alarming pace, making Karachi – the largest city of Pakistan – one of the major victims of natural gas shortfall. The purpose of this paper is to model natural gas demand and supply using geographic information systems.

Sui Southern Gas Company datasets were used to derive annual per capita gas usages and to analyze the capacity of gas supplies. Union Council is taken as a smallest and basic analytical administrative spatial unit for appraisal of badly affected, with insufficient, low and better gas supply regions.

Results show that the per capita demand for natural gas is higher in high class residential areas while supply is lowest for upper middle and lower middle class residential area populations. Only 19 per cent of the total residential areas are expected to be free from gas shortfalls. About 53 per cent of residential areas are facing the problem of low gas availability; and 3 per cent and 11 per cent areas are under stress of badly affected and insufficient gas supply, respectively.

This research shows an example of constructing a Geographic Information System (GIS)‐based gas demand and supply model that can be used for building strategic guidelines for top‐level planners, engineers and decision makers at the micro‐level. This is not a “deep” paper, but it works in identifying a problem and presenting a quantitative way forward. This paper will have significant impact both on society and academia, as this innovative technology and its implementation on gas utility has happened for the first time in Pakistan. Furthermore, in the international literature this has also been in infancy and will open new avenues of research, especially in developing countries. The work would certainly be applicable for other consumer‐based utilities such as electricity, telecommunication, sewerage and municipal water and they would all benefit from it substantially.

This study seeks to investigate the multidimensionality person‐group (PG) fit. It first aims to examine values‐based, personality‐based, and KSA‐based fit as distinct PG fit dimensions. It then also aims to examine fit as an aggregate construct (each dimension combines to form a latent PG fit construct), and as a superordinate construct (an overarching assessment of compatibility drives the individual fit dimensions). It also aims to propose that the distinct dimensions or the overall perception predict commitment to team, employee voice, and knowledge sharing, resulting in a final outcome of employee task performance.

Data were collected using longitudinal survey methodology from three different sources (793 employees, their supervisors and the Human Resources department) in a manufacturing firm in Korea. The various models were evaluated using structural equation modeling.

The distinct dimensions model, in which values‐based fit predicted commitment to the team, personality‐based fit predicted voice behaviors, and KSA‐based fit predicted knowledge sharing, was mostly supported. Each of these intermediary factors predicted supervisors' ratings of individual task performance. Although each dimension had unique impact on the outcomes, results suggested that a superordinate PG construct might be driving the more specific fit assessments. The aggregate model was not supported.

This study is the first to show how different dimensions of PG fit may differentially influence affect and behavior, to predict task performance. It also shows the first evidence for PG fit as a superordinate multidimensional construct. Results provide a basis for new knowledge regarding the multi‐faceted relationship between fit perceptions and outcomes.
