Abstract

Purpose

Significant transitions in firms (e.g. outsourcing) may impact the relative importance of production and inventory assets, affecting the hierarchical separation of planning decisions. The purpose of this paper is to contribute to planning literature by investigating how the production system and the planning environment influence the performance difference between hierarchical and monolithic planning. Further, it seeks to reduce the prevailing theory-practice gap in tactical planning.

Design/methodology/approach

Through an action research study, a monolithic model integrating tactical production planning decisions, subject to upstream supply chain constraints, with strategic investments decisions was developed, tested and implemented in a global OEM. Using the developed model and a measure of the capital cost of production assets relative to the cost of holding inventory, it is numerically examined how the production system and planning environment influence the performance of hierarchical and monolithic planning.

Findings

The research demonstrates the potential of integrating decisions and reveals significant performance differences between hierarchical and monolithic planning for firms with low capital cost relative to inventory holding cost.

Research limitations/implications

The findings suggest a fit between planning processes, the production system and planning environment. Future research should empirically validate the findings and propositions.

Originality/value

The paper combine capital investments and production planning decisions, which usually transpire at different hierarchical levels and on different time-horizons, and investigates the consequences of hierarchical separation through a real-life validated case and numerical analysis.

Abstract

Some hierarchical approaches for production planning in a batch type manufacturing environment are described. In a single stage production system, three aggregation levels exist: types, families and items. The performance of a hierarchical system model is largely dependent on the methods of disaggregation at different levels. This paper reports on a study of hierarchical methods at the family disaggregation level and incorporates a simple modification to improve upon a heuristic proposed by Winters. Results indicate that even a very simple hierarchical planning approach can give a significant reduction in backorders in a production shop having severe capacity restriction.

Abstract

Purpose

The purpose of this paper is to develop new simple logics and translations for hierarchical model checking. Hierarchical model checking is a model-checking paradigm that can appropriately verify systems with hierarchical information and structures.

Design/methodology/approach

In this study, logics and translations for hierarchical model checking are developed based on linear-time temporal logic (LTL), computation-tree logic (CTL) and full computation-tree logic (CTL*). A sequential linear-time temporal logic (sLTL), a sequential computation-tree logic (sCTL), and a sequential full computation-tree logic (sCTL*), which can suitably represent hierarchical information and structures, are developed by extending LTL, CTL and CTL*, respectively. Translations from sLTL, sCTL and sCTL* into LTL, CTL and CTL*, respectively, are defined, and theorems for embedding sLTL, sCTL and sCTL* into LTL, CTL and CTL*, respectively, are proved using these translations.

Findings

These embedding theorems allow us to reuse the standard LTL-, CTL-, and CTL*-based model-checking algorithms to verify hierarchical systems that are modeled and specified by sLTL, sCTL and sCTL*.

Originality/value

The new logics sLTL, sCTL and sCTL* and their translations are developed, and some illustrative examples of hierarchical model checking are presented based on these logics and translations.

The purpose of this paper is to frame collaboration in supply chain as a hierarchical reflective construct.

Abstract

Purpose

The purpose of this paper is to frame collaboration in supply chain as a hierarchical reflective construct.

Design/methodology/approach

This study uses data from industries in India to test the hierarchical and structural model. Partial least squares method is used to test the model.

Findings

Results show that collaboration is a third‐order, reflective construct. The paper's findings also arrange collaborative activities in terms of its importance for collaboration.

Practical implications

Collaboration is a multi‐facet activity and is a meta‐concept, and therefore this paper improves our understanding on the subject. The performance of supply chain collaboration depends on the execution of various activities, and this paper points out how the various activities are related to the collaboration, the execution of which will drive collaborative ventures towards success.

Originality/value

This paper provides empirical evidence for collaboration as a hierarchical reflective construct. The model is tested by data collected from Industries in India.

Abstract

This paper discusses a knowledge based information retrieval model with hierarchical thesaurus. The model computes the conceptual distance between a query and an object and both are indexed with weighted terms from a hierarchical thesaurus. The hierarchical thesaurus is represented by a hierarchical‐concept graph (HCG) in which nodes represent concepts and directed edges represent generalisation relationships. Rada et al. have developed a similar model. However, their model considered only a binary indexing scheme and revealed some counter‐intuitive results. Our proposed model extends theirs by allowing the index term and the edge of the HCG to be weighted. A new concept mapping method is devised to overcome Rada's counter‐intuitive results. In addition, a scheme for allowing Boolean operators in user queries is provided with a formula for computing conceptual distance from negated index terms. Experimental results have shown that our model simulates human performance more closely than Rada's model.

Abstract

We present a simulation designed to capture the impact of both formal authority ties and informal socialization ties on the performance of an organization adapting to a turbulent world. We present a summary of three key models that informed our approach and then outline and describe the operation of our resulting simulation. Using an experiment that manipulated both the authority network structure and the stress the organization placed on socialization, we show inefficient authority structures harm performance, and also that socialization has a strong and nonlinear impact on peak organizational performance and on the performance of top management. We also present a case study, instantiating the general model with the specific context of a real-world organization. Finally, our integrated multimodel suggests that companies should pursue different strategies in hiring key strategic actors than they do for other actors.

Abstract

The latest financial crisis has stressed the need of understanding the world financial system as a network of interconnected institutions, where financial linkages play a fundamental role in the spread of systemic risks. In this paper we propose to enrich the topological perspective of network models with a more structured statistical framework, that of Bayesian Gaussian graphical models. From a statistical viewpoint, we propose a new class of hierarchical Bayesian graphical models that can split correlations between institutions into country specific and idiosyncratic ones, in a way that parallels the decomposition of returns in the well-known Capital Asset Pricing Model. From a financial economics viewpoint, we suggest a way to model systemic risk that can explicitly take into account frictions between different financial markets, particularly suited to study the ongoing banking union process in Europe. From a computational viewpoint, we develop a novel Markov chain Monte Carlo algorithm based on Bayes factor thresholding.

Abstract

Purpose

This paper aims to test the general validity of a hierarchical model of country image conceptualizations across countries that differ in socio-economic development and distance to the exporting country.

Design/methodology/approach

Representative consumer samples in Germany, France, China and Thailand (N ∼ 1,000 per country) completed an online survey on three levels of country image regarding Denmark and attitudes towards buying an organic food product from Denmark. Data were analyzed using confirmatory factor analysis and structural equation modelling.

Findings

The hierarchical country image model fitted the data well in the two European countries, but not in the two Asian countries. It appears that the hierarchical relationships proposed by the model require a high level of familiarity with and knowledge of the origin country and the product type.

Research limitations/implications

The application scope of the model is considerably narrower than implied by earlier research. Further research should combine data from a number of sources to investigate the model’s application further.

Practical implications

Exporters must pay attention to both the general image of their country and the image of their country with regard to their specific product category, as this impacts consumer product evaluations.

Originality/value

International trade and the success of export strategies ultimately depend on consumer acceptance in importing countries. This study demonstrates how consumer perception of imported products is affected by the exporting country’s image, which may be more or less elaborate and differentiated. It gives exporters new insight into how they can make their marketing effective when entering markets.
