The purpose of this paper is to model the relationship between 11 frankfurter physical properties and their sensory scores to classify a release of frankfurter production batches to the market.

Data from 209 frankfurter batches were collected. Market batch release classifications were based on 11 physical properties via predictive and direct classification models. The predictive models under study included a regression, backpropagation neural network (BPN) and radial basis function neural network (RBFN) whereas the direct classification models were logistic regression, BPN and RBFN. Model performance was evaluated via correct classification rate.

The 11-7-4 RBFN predictive model proved superior with a 90 percent correct classification rate and 0 percent producer risk while the 11-5-1 RBFN, as a classification model, outperformed with the same level of accuracy, 90 and 0 percent, respectively. Producers prefer the less time-consuming direct classifiers for evaluation. Furthermore, the 11-5-1 RBFN direct classifier revealed that color measurement greatly influenced frankfurter batch release. Increases in redness, yellowness and brownness increased batch release probability.

This research attempts to establish a novel production batch release model for sausage manufacturing. Key factors can then be optimized for improving batch release probability for implementation throughout the sausage industry.

The vehicle development process (VDP) is iterative in nature with numerous interactions and information flows between design groups and between development phases. The VDP has been changed from a sequential‐functional development to a concurrent‐team based approach. Concurrent execution of design activities may reduce the development lead‐time, but it increases the managerial complexity in the VDP. A system dynamics model was developed to understand the transient behavior of parallel, overlap, and sequential processes in the VDP and to determine the optimal level of overlapping considering the development lead‐time and total number of reworks. The simulation results showed that different execution processes should be used, depending upon the intensity of reworks.

This research aimed to investigate the information-seeking behaviour (ISB) and information needs of different professional groups within the pharmaceutical manufacturing sector in the Republic of Ireland (i.e. for what purpose information is acquired), the information sources professional groups use (including in-house documentation, regulations, industry guidelines, standards and colleagues) and the factors, which influence professional groups' choice of information sources. Furthermore, the research explored the perceived level of support that exists towards knowledge and information sharing.

A quantitative non-experimental research design, comprising of a self-completion survey questionnaire, was used to examine a number of information-seeking variables: information triggers, information sources and source influencers as well as information sharing enablers. It was related to four professional tasks: process technology/process development, regulatory support and quality/compliance support and engineering.

The research provides new insights into the ISB of pharmaceutical professionals working within a highly regulated and high-performance production environment, including a greater understanding of the context in which professional groups experience information needs. The levels of agreement observed in relation to employees' perception of information-sharing enablers indicated an overall positive level of information sharing.

The study points to largely echoed previous findings which suggest that individual work role associated tasks prompt particular information needs. Further to this, work role associated tasks have a bearing on information source selection. Pharmaceutical professionals engaged in positive levels of information and knowledge sharing, relying on procedures, other colleagues and internal documentation as information sources. The participants also indicated a high level of agreement in respect to the value of available subject matter experts as information-sharing enablers.

Organisations should aim to create opportunities for adequate time to share information and organisational structures, facilitating an overall organisational culture of sharing. A focus on information sharing through forums, seminars, meetings and working groups could enhance information sharing, through the development of communities of practice.

Pharmaceutical professionals relied on trustworthiness and quality as professional' top information source-influencing factors. Furthermore, the study demonstrated that working within a high-performance, target-driven and time-constrained production environment brings a particular contextual impact, where frequent urgent information triggers are experienced. These contextual factors warrant further investigation.

A paucity of information exists with respect to the ISB of professionals, working within the pharmaceutical manufacturing sector, which is a sector known for its high level of information use and production. This paper offered an original empirical investigation of the ISB of professionals, working within the pharmaceutical manufacturing sector in the Republic of Ireland, focussing on key professional tasks. The research also addressed the level of support available for knowledge and information sharing.

SEPTEMBER sees most librarians again at the daily round, although some, including those of the universities and schools, are still scattered on mountains, golf‐courses, beaches and oceans for a short while yet. To older men there is a curious feeling aroused by the knowledge that there is no Library Association Conference this month. They may, in a measure, find compensation in attending the annual meeting of the London and Home Counties Branch of the Association, which will be at St. Albans, or that of A.S.L.I.B., which has Gonville and Caius College, Cambridge, as its venue. Both, by some lack of care which might have been avoided, occur on the same week‐end, September 24–26. Quite clearly the special problems of librarianship technique, such as processes, book‐selection and purchase, classification, catalogues, fines, publicity, salaries, hours, and so on almost infinitely, can no longer be discussed profitably at the Annual Meeting of the Library Association; smaller gatherings, such as these, are their fitting place. We make a suggestion to the L.A. Council, for what it is worth and without pretence to being original. It is that it should indicate to all its branches and sections the main questions to which they should devote attention, and that in due course they should produce their conclusions on them. These, being pooled, would form the basis of the L.A. Annual Meeting. This would make a purposeful programme for all, and the results of the Conference might then be considered definite and practical.

Much research has been reported on the possibilities of using various heuristic priority rules to sequence batches through a job shop. The SPT (Shortest Priority Time) heuristic, or modifications to it, has been proved useful in many studies. This paper reports on the results obtained when simulating the work flow through a real machine shop. The simulation model has been used to test the effect on well known priority rules of releasing batches into the shop in order of decreasing expected throughput time. The important effect of this “phased release” of batches was to increase the percentage of batches delivered in finished parts stores on time, particularly in the case where priority rules were in use which might otherwise have resulted in poor delivery. This has important repercussions for management because it implies that by “phased” release of batches in the manner discussed, a large proportion of batches will be delivered on time whatever priority rule is in operation in the shop.
