Abstract

Purpose

This paper aims to introduce a new mixed integer programming formulation and associated heuristic algorithm to solve the Military Nodal Capacity Problem, which is a type of supply chain network design problem that involves determining the amount of capacity expansion required at theater nodes to ensure the on-time delivery of military cargo.

Design/methodology/approach

Supply chain network design, mixed integer programs, heuristics and regression are used in this paper.

Findings

This work helps analysts at the United States Transportation Command identify what levels of throughput capacities, such as daily processing rates of trucks and railcars, are needed at theater distribution nodes to meet warfighter cargo delivery requirements.

Research limitations/implications

This research assumes all problem data are deterministic, and so it does not capture the variations in cargo requirements, transit times or asset payloads.

Practical implications

This work gives military analysts and decision makers prescriptive details about nodal capacities needed to meet demands. Prior to this work, insights for this type of problem were generated using multiple time-consuming simulations often involving trial-and-error to explore the trade space.

Originality/value

This work merges research of supply chain network design with military theater distribution problems to prescribe the optimal, or near-optimal, throughput capacities at theater nodes. The capacity levels must meet delivery requirements while adhering to constraints on the proportion of cargo transported by mode and the expected payloads for assets.

Abstract

Performance improvement for requirements planning systems is an issue which receives wide interest. Many programming approaches have been proposed to improve material requirements planning procedures. However, most of them appear to be too complex for large manufacturing problems. Alternatively it might be promising to explore the integration of materials requirements planning and capacity requirements planning. Several simple heuristics for integrated requirements planning systems are suggested. Several heuristics are offered to balance the load in the systems and several procedures presented to adjust the planned requirements so that the system will execute more smoothly. An industrial example supports the adequacy of the general concepts provided in this research. Results are presented which demonstrate the adequacy of these heuristics, and illustrate the ease of implementing the procedures into any MRP system.

Abstract

Purpose

This paper aims to describe the storage constrained, inbound inventory routeing problem and presents bounds and heuristics for solutions to this problem. It also seeks to analyze various characteristics of this problem by comparing the solutions generated by the two proposed heuristics with each other and with the lower bound solutions.

Design/methodology/approach

The proposed heuristics use a sequential decomposition strategy for generating solutions for this problem. These heuristics are evaluated on a set of problem instances which are based on an actual application in the automotive manufacturing industry.

Findings

The storage space clearly has a significant effect on both the routeing and inventory decisions, and there are complex and interesting interactions between the problem factors and performance measures.

Practical implications

Facility design decisions for the storage of inbound materials should carefully consider the impact of storage space on transportation and logistics costs.

Originality/value

This problem occurs in a number of different industrial applications while most of the existing literature addresses outbound distribution. Other papers that address similar problems do not consider all of the practical constraints in the problem or do not adequately benchmark and analyze their proposed solutions.

Abstract

An attempt is made to classify the lot‐sizing problem based on evidence from the literature and current research trends. For future research a mixture of a heuristic method to find a sequence and cycle time and a mathematical program to find lot sizes would be feasible even for fairly large problems. Attempts should be made to apply marginal analysis in practical lot‐sizing problems since it may result in lower cost solutions.

Abstract

The cognitive composition process of attribute information plays a critical role in heuristic aspects of consumers’ multiattribute preferential decisions. This study examines the effects of attribute information order and attribute information amount on consumers’ multiattribute preferential decisions under the premise of consumers’ limited information processing capacity. An experiment with two separate designs is conducted for testing the different hypotheses. The results support the hypothesis that consumers’ multiattribute preferential decisions are influenced by the amount of attribute information received/processed. The attribute information order is found to affect not only the outcomes of consumer decisions but also the amount of attribute information processed. These findings further suggest that consumers may be more inclined to adopt strategies of a noncompensatory heuristic nature when making multiattribute preferential decisions.

Abstract

Considers the availability of objective criteria for creativity enhancement from relevant applied research. Uses research to address the problem of creativity within the framework of artificial intelligence. Compares thinking to using a map and discusses creativity in terms of making our own maps rather than just following existing maps. Suggests that creativity includes the individual′s mastering of existing rules, enabling him or her to see when these rules might be broken. It thus follows that basic heuristic competences underlie the creative act. A strategy for stimulating creativity should include a more systematic basis for the development of creative resources, in the concept of heuristic competence.

Abstract

Polarica is a company in northern Europe buying, refining and selling wild berries and other specialty foods. During the last couple of years the volume of wild berries, mostly blueberries, has increased a lot. This expansion forces Polarica to consider investments in freezing‐in capacity and cold‐storage capacity. A simple heuristic model was constructed, from which it was concluded that additional volumes of frozen blueberries require more storage facilities and it was also recommended that the location should be based on load‐distance analysis. The way this problem is tackled and solved can be copied and hopefully it presents ideas for other similar studies.

Abstract

Purpose

The purpose of this study is to propose and formulate an integrated hierarchical production, and maintenance‐planning model.

Design/methodology/approach

The proposed model is formulated mathematically and tested for some hypothetical cases. A two‐level planning is proposed to address the hierarchical planning problem, i.e. aggregate planning and detailed planning. A preventive maintenance planning is integrated into the aggregate planning, while machine breakdowns, which require corrective maintenance actions, are investigated in the detailed planning. The proposed general preventive maintenance model is tested against cyclical preventive maintenance models for some cases, and for evaluating the performance of the models, in terms of costs, and service levels.

Findings

The proposed general preventive maintenance model gives a better solution in terms of cost than the cyclical maintenance model (i.e. 6 per cent less costly), if the maintenance planning is executed separately from the production planning. In terms of service level, however, both models perform equally well with average service levels equal to 97.6 per cent. The effect of tight capacity, long maintenance duration, and small machine parameters similarly tightens the capacity. In these cases, it is shown that a stable level of capacity is more beneficial to achieve a better service level, which is gained if the preventive maintenance actions are carried out monthly.

Practical implications

At the aggregate level, the proposed preventive maintenance model considers a non‐cyclical planning, which means that the preventive maintenance periods do not necessarily fall at equally distant times. The inventory movement constraints at the aggregate level decouple machines to operate independently; hence the detailed level problem can be solved separately for each machine. In a rolling horizon approach, only the first period of the aggregate plan is implemented and disaggregated into the production of items at the detailed level.

Originality/value

The paper proposes an integrated model of hierarchical production and maintenance planning. A general preventive maintenance is integrated into the aggregate planning, while machine breakdowns are investigated in the detailed planning. To the best of one's knowledge, such a hierarchical view of production planning and maintenance has not been addressed adequately.

Abstract

Purpose

The purpose of this paper is to contribute to research on the impact that the creation of value theory has on professional, organizational, and economic performance. However, a special emphasis is on explicating the theoretical foundation of the concept.

Design/methodology/approach

This paper is based on a hermeneutic study of the relationship between value creation and managing economic resources. The paper traces the value creation concept to its roots from the foundation of Western Civilization through the value theory of Adam Smith and up to recent technological age advancements in value theory.

Findings

Since its emergence the value concept has been explicated in an abundance of literature. However, there has been very little in regards to explanations detailing the theoretical underpinnings of the concept. According to John Stuart Mill, attempts to apply value theory will fail (due to misinformation or inaccurate information) without inclusiveness of the full scope of what is relevant for social science and social economic research.

Research limitations/implications

Although studies on organizational behavior encompass the economic aspects of research economic research tends to be narrower in scope making it difficult to verify some value claims in economic terms. This is especially true in terms of making claims in regards to the connection between economic value theory, social value theory, the Philosophy of Economics, and the Philosophy of Science.

Practical implications

The study introduces a theoretical framework for integrating the value added and value creation concepts as a strategy for increasing shareholder benefits, stakeholder capital, and social capital.

Social implications

The paper explains how the value creation concept contributes to an increase in wealth, prosperity, flourishing by drawing from a technological age approach to value creation.

Originality/value

The paper fills the void in the literature regarding the theoretical framework of the concept thus undergirds claims about its practical benefits by clarifying its theoretical framework.
