These included plants processing raw meat and salads, Chinese ready meals, dairy products, slicing and packing of cooked meats and catering establishments. An initial survey of total numbers of microbes at a total of 891 sites on evaporators, drip trays and chilled room walls was followed up with a more detailed examination of 336 sites with high counts, selecting for Listeria spp., coliforms, enterococci, Staphylococcus aureus and Bacillus cereus. Temperatures (particularly air on and air off, maximum and near defrost heaters) relative humidity, airflow, layout and cleaning regimes were surveyed. In general, no correlation could be found between any of the physical measurements and the numbers and types of bacteria detected. Maximum mean temperatures in the chilled rooms varied from ?1 to + 176。Original Research ArticleJournal of Manufacturing SystemsScheduling belongs to the special class of NPhard problems for which no polynomial time algorithm has been found. Therefore, a schedule that is the best possible nearoptimal solution is often acceptable. This paper presents a scheduling approach, based on Genetic Algorithms (GAs), developed to address the scheduling problem in manufacturing systems constrained by both machines and workers. This genetic algorithm utilizes a new chromosome representation, which takes into account machine and worker assignments to jobs. A set of experiments for determining the best staffing level and machine and worker assignment to jobs was performed. A study was conducted using dispatching rules with various performance measures for two types of shop characteristics: (i) dualresource (machines and workers) constrained, and (ii) singleresource constrained (machines onl
