Modellgestützte Flexibilitätsanalyse von Strategien zur Ersatzteilversorgung in der Nachserienphase

An important task in after sales service is the provision of spare parts for durables. Due to its nature and dependence on earlier sales, the demand for spare parts is inherently dynamic and uncertain requiring for high procurement flexibility. During the product life cycle, inventory management of spare parts is performed efficiently under use of flexibility provided by existing production facilities. This situation completely changes once the OEM ceases production of the parent product. A prime option of procuring spare parts for the End-of-production period is to place a final order for parts when regular production ends. Besides low unit production costs, this option does not contain any flexibility, yielding a high risk of obsolescence of stored parts, and at the same time a high risk of not being able to satisfy all demand during the service period. In order to increase flexibility further options like extra production at higher unit cost or remanufacturing of components taken from used products could be used. After introducing the problem and a basic quantitative model, we evaluate flexibility properties of strategies using different combinations of the above options. In doing so we distinguish between quantity, time, and stock related flexibility. In a comprehensive numerical study it is investigated to which extent flexibility properties of the different strategies can contribute to their economic profitability.     

Interrupting Trauma and Advancing Development: Considering Parent Education in Contemporary Psychoanalytic Treatment

This paper centers on the exploration and utilization of a contemporary, psychoanalytically-based parent education perspective aimed at interrupting intergenerational trauma. It highlights The Parenting Process, an integrative model of parent education that is at once educational and therapeutic. This model is explored in light of a third listening stance based on James Fosshage’s listening perspectives concept. This paper underscores and illustrates through clinical material the benefits of playing with implicit and explicit communication across various sensory modalities.     

Hierarchische Planung für industrielle Logistikdienstleister

In this paper a planning and control system for logistics service providers (called LPS system) is developed under consideration of their specific flexibility potentials. Due to the complexity of such planning decisions (different planning levels and data quality of these levels as well as time horizons etc.), a multi-stage, hierarchical planning system is proposed which minimizes the relevant costs under consideration of the flexibilities. The advantage of a hierarchical planning concept consists in a limited planning complexity because otherwise data collection and solution development would lead to unsolvable problems in practice. The results of using LPS systems for a real-life case show a significant pay-off for logistics service providers due to the remarkable cost savings by applying a hierarchical planning concept.     

Leitung mit Supervisionskompetenz

The author describes a position of a supervisor in a clinical institution, which he would have rejected some years ago??to adopt a management role as supervisor and to act mainly in the role of a supervisor. But the recent experiences have shown, that this may be possible and successful. This is illustrated by a case study.     

Personnel selection criteria in IT ventures: A policy-capturing analysis

Growing ventures need to hire new employees and thus enhance their human capital stock. Selecting the right employees is crucial for the firms’ success. This paper looks at the criteria used in the selection process, especially at applicant fit, competencies, and social capital. Using a policy-capturing approach on a sample of managers in the German informationtechnology industry, the paper provides empirical evidence of the relationship between firm age and person-organization fit in the selection process. Furthermore, it demonstrates the interaction between two sets of selection criteria: applicant competencies and applicant fit with the formal job-requirements.
