    The main objective of this research is to contribute to the development of a Performance Measurement System (PMS) foragri-food supply chains that involves the entire chain (i.e. all stages starting from raw materials to retailers) and includes a comprehensive set of performance indicators. For this purpose, Dutch vegetable supply chains have been chosen as case study. The research started by looking at the factors influencing the performance of Dutch vegetables growers. The results show that the choice of marketing channel has an impact on the performance of growers (i.e. growers who used mixed marketing channels, on average, were relatively more efficient than those who sold their total produce through auctions).

    The next step of the research was a literature review on existing performance indicators and models in the supply chain literature. Based on this literature review a conceptual framework for measuring performance ofagri-food supply chains is developed which includes financial, as well as non-financial indicators combined with specific characteristics ofagri-food supply chains. The conceptual framework is evaluated in a Dutch-German tomato supply chain and further developed into a condensed model with only the key performance indicators. The results show that efficiency, flexibility, responsiveness and food quality are four key performance components and form the basis for a PMS foragri-food supply chains.

    The application of the conceptual framework is carried out by looking at the perceived impact of different requirements of Quality Assurance Systems (QAS) on the performance of a Dutch tomato supply chain. Results indicate that some QAS requirements are perceived to have a positive impact on some supply chain members' performance, while they are perceived to have a negative impact on other chain members' performance. Overall, results revealed that all selected QAS requirements are perceived to have a positive impact on the performance of the supply chain, although the total impact is relatively small. The PMS framework applied in this study provides an insight in the impact of QAS requirements on performance. In addition, the PMS framework allows to make tradeoffs between different performance dimensions within the own firm, as well as throughout the chain.

    Benchmarking procedure for full-scale activated sludge plants

    To enhance development and acceptance of new control strategies, a standard simulation benchmarking methodology to evaluate the performance of wastewater treatment plants has recently been proposed. The proposed methodology is, however, for a typical plant and that works under typical loading and environmental conditions. Thus, benchmarking a full-scale plant working under different situations is still a problem that needs to be solved. This paper proposes a data based approach to benchmark any specific full-scale activated sludge plant used for carbon and nitrogen removal and using real design, operational and performance data. The advantage of the proposed approach over the "one-typical-plant" approach, is that it takes into account the very specific design and operational characteristics of the plant that will be benchmarked. A real-world illustrative example is also presented in this paper

    De Dierveiligheidsindex is ontwikkeld met het doel om op het primaire bedrijf de risico’s op insleep en verspreiding van dierziekten versneld terug te dringen en het gezondheids- en welzijnsniveau versneld te verbeteren. De Dierveiligheidsindex (DVI) is een meetinstrument voor varkensbedrijven waarmee met behulp van checklists inzicht wordt verkregen in de aandachtsvelden contactstructuur, diergezondheid en dierenwelzijn. Ieder aandachtsveld is onderverdeeld in drie niveaus van oplopende zwaarte (DVI-1-, DVI-2- en DVI-3-niveau). Het DVI-niveau 1 omvat twee typen voorschriften: de basisvoorwaarden waartoe onder andere de wetgeving behoort en DVI-1-voorschriften. Er is van medio 1999 tot medio 2000 een praktijkproef uitgevoerd met als doel een indruk te krijgen van 1) de haalbaarheid van de verschillende DVI-niveaus bij aanvang van de proef, 2) de mogelijkheden om met behulp van de Dierveiligheidsindex binnen een proefperiode van circa een jaar door te groeien naar hogere niveaus van diergezondheid en dierwelzijn en 3) de praktische uitvoerbaarheid daarvan
