    AN ANALYSIS OF CAPACITY PLANNING PROCEDURES FOR A MATERIAL REQUIREMENTS PLANNING SYSTEM (1984)

    Notes: This paper is concerned with planning work-center capacity levels in manufacturing firms that employ a material requirements planning (MRP) system. It presents four procedures for developing work-center capacity plans designed to insure the production of components and assemblies as specified by the MRP plan and the master production schedule (MPS). These procedures (capacity planning using overall factors, capacity bills, resource profiles, and capacity requirements planning) are compared using simulation analysis. The results indicate that the performance of a procedure when measured against the MPS depends on the operating conditions of the manufacturing system. The results also indicate that the choice of a particular procedure often represents a compromise among the benefits of improved MPS performance, the costs of preparing and processing data, and the premium expenses required for more frequent adjustments in work-center capacity levels.

    A FRAMEWORK FOR THE SYSTEM DESIGN PROCESS (1972)

    Notes: Much discussion and writing about “systems” is often superficial, glib, and of a non-operational nature. This paper presents a cohesive framework for the process of system design which is felt to be of operational value in the design and management of systems.The framework's central tenet is that all systems are made up of entities and the relationships among the attributes of those entities; and that in designing systems, two processes are used, inclusion and structuring. Inclusion is concerned with what entities to include in a system and structuring with how their attributes are to be related. The system design process is directed or driven by a set (system) of criteria. Systems must be viewed with a time dimension: evolution will and should take place, both in the systems themselves and, more importantly, in the criteria that drive the design and evolution of those systems. In this framework, all problem solvers can usefully regard themselves as system designers.Presentation of the framework is followed by examples, discussion of the criteria set, system design tools, and some implications for teachers and practitioners.

    ON PREDICTING COMPUTATIONAL TIME OF A BRANCH AND BOUND ALGORITHM FOR THE ASSIGNMENT OF FACILITIES (1976)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Experience with branch and bound algorithms indicates that computational time is a function of not only the size of the problem, but also the nature of the input data. This paper formulates statistically-based variables which describe certain characteristics of the input data and experimentally evaluates their ability to predict computational time for one branch and bound algorithm, the relative location of facilities or “plant layout” problem. Results suggest that the described experimental procedure may be useful for an a priori assessment of the computational difficulty of specific branch and bound problems.

    Seed protein content of soybean as affected by spatial variation in field experiments (1996)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: The variation of soybean seed protein content has been investigated in performance trials of maturity group 000 to I genotypes at different locations in the eastern part of Austria between 1992 and 1994. In all experiments evaluated, significant portions of spatial variation were identified which affected seed protein content in the range of −25 to +30 g/kg. Lattice and neighbour analysis were more efficient than the randomized complete block design in reducing error variance in most experiments. Neighbour analysis was superior to the lattice design when soil trends were changing over short distances or in both longitudinal and latitudinal directions. In most instances, neighbour analysis based on two or three neighbouring plots at each side of a test plot was more efficient than an analysis using only the nearest neighbours. Residuals derived from neighbour analysis were also used to visualize spatial heterogeneity, and clear trends of protein content were identified for particular experimental sites. The ranking of genetic entries was considerably biased by spatial variations, which would have reduced the efficiency of selection for high protein content if genotype performance was not adjusted for field variation.

    The presence or absence of the soybean Kunitz trypsin inhibitor as a quantitative trait locus for seed protein content (2002)

    Notes: Numerous quantitative trait loci (QTL) for various characters have recently been reported in different crop plants. However, information is limited about the molecular mechanisms behind QTL, because most of them have only been detected at a statistical level. Therefore, progeny from a cross between two soybean genotypes segregating for the presence vs. absence of the Kunitz trypsin inhibitor, a 21.5 kDa protein, have been analysed for possible effects of that protein on agronomic and seed quality characters. Protein content was reduced by, on average, 4.5 g/kg in segregants lacking the Kunitz protein, whereas oil content and other characters remained unaffected. This finding can be interpreted as a ‘model QTL’ for variation in seed protein content, because the molecular and genetic backgrounds of the soybean Kunitz trypsin inhibitor are well understood.

    Genetic diversity in camelina germplasm as revealed by seed quality characteristics and RAPD polymorphism (2005)

    Notes: Camelina is an alternative oilseed crop species with limited information about the origin and diversity of available germplasm. Therefore, a set of 130 camelina accessions from a world collection was evaluated for oil content, protein content and 1000-seed weight in field experiments grown in three macro-environments in Austria. Based on phenotypic data, accessions were categorized into four groups with different seed characteristics using k-means cluster analysis or principal component extraction. Subsequently, a representative set of 41 accessions was subjected to random amplified polymorphic DNA (RAPD) analysis. Of 24 primers, 15 were polymorphic producing a total of 30 marker loci. Genetic distance estimates between the 41 accessions were calculated, based both on RAPD polymorphism and on seed quality characteristics, and dendrograms were generated for comparison. Similarities were found between the two different clustering approaches, and grouping was partly in agreement with pedigree information or geographic origin. However, as the two estimates of diversity sampled different segments of the genome, i.e. regions coding for seed characteristics or phenotypically neutral genomic regions highlighted by discrete markers, the correlation between the two distance matrices was low.

    Genetic diversity in soybean as determined by RAPD and microsatellite analysis (1997)
    Oxford, UK : Blackwell Publishing Ltd
    Plant breeding 116 (1997), S. 0 
    Details
    ISSN: 1439-0523
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: The random amplified polymorphic DNA (RAPD) and microsatellite techniques were used to evaluate the genetic diversity among 18 soybean genotypes selected for a breeding programme to increase the protein content of varieties adapted for central European growing conditions. Out of 33 random primers used in RAPD reactions, only 12 showed polymorphism useful for characterization of these genotypes. In contrast, all 12 microsatellite primer pairs used in this study detected polymorphism with 2–6 alleles per locus. Similarity measures and cluster analysis were made using RAPD and simple sequence repeat (SSR) data, separately and together. The resulting dendrograms were compared with each other and with the available pedigree information as a control. The dendrogram derived from RAPD data showed some divergence from the pedigree information available for the lines. The dendrograms based on SSR data and SSR data combined with RAPD gave very good agreement with pedigree information. It can be concluded that the combined use of a limited number of RAPD and SSR markers is a useful and reliable means of evaluating genetic relationships of genotypes in the absence of pedigree data.

    Chronic psychosocial stress differentially affects apoptosis in hippocampal subregions and cortex of the adult tree shrew (2001)

    Details

    Topics: Medicine
    Notes: We studied the effect of chronic psychosocial stress on cell death and volume changes in the tree shrew hippocampus. In situ end labelling (ISEL) identified low frequent but convincing apoptosis in many hippocampal subregions. Also in entorhinal cortex, apoptosis was found, generally at higher frequencies. After 28 days of chronic stress, apoptosis was significantly reduced in the CA1 stratum radiatum, whereas an increase was observed in the hilus (P 〈 0.04). With all subregions taken together, the hippocampus showed a decrease, whereas in the cortex, an increase in apoptosis was found after stress (P 〈 0.04). In a parallel and similar chronic stress study, post mortem morphometry of the same brain regions was performed, revealing mild decreases (7.6%) in entire hippocampal volume. We conclude that (i) low frequent apoptosis occurs throughout the adult tree shrew brain, and (ii) 28 days of chronic stress differentially affects its occurrence in distinct hippocampal subregions and entorhinal cortex. As previous stereological investigations failed to detect any loss in the principal neuronal layers, psychosocial stress, therefore, must affect other (structural) parameters like dendritic tree, interneurons, neurogenesis, or glia.

    Notes: Using a two-round Delphi process among 92 manufacturing managers fromaround the world, assesses the appropriateness of a variety ofperformance measures. The Delphi process used a survey technique thatwas pioneered by Dixon, Nanni, and Vollmann to highlight gaps (highperceived importance to the company but low weight in the performancemeasurement system) and false alarms (low perceived importance to thecompany but high weight in the performance measurement system). Directcost reduction, machine efficiency, and labour efficiency are almostuniversally seen as false alarms. On the other hand, new productintroduction, customer satisfaction, and employee involvement arefrequently revealed to be gaps, although with less consistency.Cross-industry comparisons are a distinctive feature of this research.
