Abstract

Einführung in das Portfolio‐Management Allgemein ist in den letzten 5–10 Jahren zunehmendes Interesse der Wirtschaft und Verwaltung für Probleme der strategischen Planung festzustellen, nicht zuletzt aufgrund der Diskussion über das Portfolio‐Management. Dieses neue Planungsmodell rückt durch die Definition sogenannter Strategischer Geschäftsfelder (“business units”, vgl. Abschnitt 2 dieses Aufsatzes) als strategische Planung aus gesamtunternehmerischer Sicht in den Mittelpunkt der Betrachtung und löst sich damit los von der engen Funktionalorientierung, bei der jeder strategische Bereich als eigene und relativ unabhängige Planungseinheit auftritt. Abell/Hammond sprechen in diesem Zusammenhang von einem 3‐zyklischen Planungsprozess (Abell/Hammond 1979, S. 14) (vgl. Abb. 1); die Längeund Breite der einzelnen Planungsstufen geben gleichzeitig ihre zeitliche Dauer und ihre relative Bedeutung wieder.

Abstract

Die Anwendung strategischer Fhrungsmethoden in Hotelunternehmen ist durch zunehmende Turbulenz im gesamtgesellschaftlichen Umfeld und durch Intensivierung des Wettbewerbes in der Tourismusbranche wichtiger denn je. Unbefriedigend ist, dass die strategische Fhrung von Service‐unternehmen lange Zeit zu sehr unter dem Eindruck einer Theorie fr Unternehmen der Sachgterpro‐duktion gestanden hat. Erst in den letzten Jahren wurden in verstärktem Masse eigene Theorieansätze entwickelt, wobei bestimmte Besonderheiten von Dienstleistungen verstärkte Beachtung finden. Dazu zählt vornehmlich die “buyer/seller‐interaction”, mit simultanem Ablauf von Produktion und Konsum. Die von Gästen wahrgenommene Qualität persönlicher Dienstleistungen wird in dieser Situation massgeblich beeinflusst. Um eine strategische Managementfalle zu vermeiden, ist daher das Geschehen im Rahmen persönlicher Gästekontakte und das damit verbundene Problem einer präventiven Qualitäts‐sicherung im Rahmen von Stärken/Schwächen‐Ana‐lysen als zentraler Erfolgsfaktor zu beachten.

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

OTHER TYPES OF LANGUAGE LABORATORY 1. Laboratories without student recording facilities. To this category belong the various types of ‘milking machine’. The programme is fed to the students from the master tape recorder (or other source) via (‘audio‐active’) headsets with feed‐back from the students' microphones to their ears, although in the simplest form of this type of installation the student only possesses his headphones.

Abstract

Purpose

The purpose of this paper is to modify the crow search algorithm (CSA) to enhance both exploration and exploitation capability by including two novel approaches. The positions of the crows are updated in two approaches based on awareness probability (AP). With AP, the position of a crow is updated by considering its velocity, calculated in a similar fashion to particle swarm optimization (PSO) to enhance the exploiting capability. Without AP, the crows are subdivided into groups by considering their weights, and the crows are updated by conceding leaders of the groups distributed over the search space to enhance the exploring capability. The performance of the proposed PSO-based group-oriented CSA (PGCSA) is realized by exploring the solution of benchmark equations. Further, the proposed PGCSA algorithm is validated over recently published algorithms by solving engineering problems.

Design/methodology/approach

In this paper, two novel approaches are implemented in two phases of CSA (with and without AP), which have been entitled the PGCSA algorithm to solve engineering benchmark problems.

Findings

The proposed algorithm is applied with two types of problems such as eight benchmark equations without constraint and six engineering problems.

Originality/value

The PGCSA algorithm is proposed with superior competence to solve engineering problems. The proposed algorithm is substantiated hypothetically by using a paired t-test.
