    Notizen: Automated guided vehicle (AGV) systems provide the flexibility and integration required for flexible manufacturing systems. Previous AGV system studies have attempted to reduce the controlling complexities commonly encountered in these systems. However, this has not been accomplished without additional resources (e.g., automated guided vehicles) and lower system flexibility. The primary objective of this study is to compare the performance of AGV system configurations that reduce controlling and modification complexities (i.e., tandem configurations) to traditional AGV system configuration. Three AGV system configurations were tested under 16 experimental conditions. Performance metrics considered were AGV utilization, mean flowtime, mean tardiness, and percent tardy. The results of this study extend the findings of the previous studies in demonstrating the viability of tandem configurations, in that the tandem configurations match the performance of traditional configuration across all performance metrics, without sacrificing ease of control and system flexibility. Finally, the cost tradeoffs inherent in selecting a particular configuration are discussed.

    Notizen: This presents new theoretical and practical results derived from the author's (1974) paper on calculating 12D from inoculated packs. The theoretical portion compares methods for estimating the number of surviving organisms and shows that the Halvorson-Ziegler formula is approximately derivable from the theory given previously. The more practical part shows several examples of what may hapen if the organism death kinetics are shifted-rather than simple exponential. A new test procedure is outlined that should lead to more reliable estimates of 12D than are now obtained.

    Notizen: This paper presents a formulation in dimensionless terms of the equations pertaining to first-order processes that follow Arrhenius kinetics, and applies them to problems in food thermoprocessing. the need for it arose from attempts to understand the relation between destruction of pathogenic microorganisms and formation of chemical markers in the food. During processing food is subjected to a thermal pulse that affects the markers and microorganisms. the dimensionless formulation makes it convenient to obtain equations expressing the relation between the decadic reduction in microbial population and the rise in marker concentration for temperature-time profiles of forms hitherto not conveniently calculable. Measurements of chemical markers can be used with these formulas to predict destruction of microorganisms. Examples are given of calculations demonstrating the feasibility of this approach when a single marker is monitored.

    Notizen: Corn meal extrudates were produced using process conditions designed to obtain various product structures. Extrudates were infused with a particle-containing, high melting point lipid suspension, a process used to produce calorically dense components for military rations. Image analysis was used to estimate the degree of particle penetration into the extruded matrices and determine cell size distributions. Infusion uniformity was correlated with structural attributes, such as density, expansion, and average cell size.

    Notizen: Vacuum infusion of porous food matrices (i.e., extruded starch crackers) with calorically dense suspensions of food powders in fat was investigated in an ideal system. Experiments involved infusion of model matrices with lipid suspensions consisting of milled, size-characterized sucrose in corn oil. The influences of pore size/particle size ratio and suspension concentration on the penetration of liquid and particles were determined. A mathematical model that allows prediction of future behavior was fitted to the test results. The model indicates that dry-weight particle penetration is strongly correlated with pore size and independent of initial particle concentration. Infusion of liquid plus particles was increased by raising porosity and lowering particle concentration.

    Notizen: A study of a new military ration, the Meal, Ready-to-Eat, Individual (MRE) after 2 yr of storage at four different temperatures was conducted. The main emphasis is on the statistical analysis of data on consumer-acceptance, in particular the estimation of shelf-life. The principal finding is that the ration as a whole can be stored for at least 2 yr at temperatures up to 38°C without serious loss of acceptance, although a few individual items may be affected.
