Reactive repair of a disrupted schedule is a better alternative to total rescheduling, as the latter is a time consuming process and also results in shop floor nervousness. The schedule repair heuristics reported in the literature generally address only machine breakdown. This paper presents a modified Affected Operations Rescheduling (mAOR) approach, which deals with many of the disruptions that are frequently encountered in a job shop. The repair of these disruptions has been decomposed into four generic repair actions that can be applied singularly or in combination. These generic repair actions are evaluated through a simulation study with the performance measures of efficiency and stability. The results indicate the effectiveness of the mAOR heuristic in dealing with typical job shop disruptions. / Singapore-MIT Alliance (SMA)

In this thesis, repair and positioning are examined with respect to second language learners. The data employed in this analysis consists of oral examinations taken by students of German. These data comprise 22 tape recordings averaging 10 minutes in length. The students’ level of German language proficiency is understood to be intermediate. Conversation analysis is the methodology used to analyse the recorded spoken data. The data is first discussed within the context of research on focus on form, including research on learner uptake. To provide new insights in this discussion, the analysis goes further to include the perspective of positioning theory, in particular the aspect of different storylines. Taking interactional repair as the focus of discussion, my analysis shows that form cannot always be strictly separated from meaning when it comes to repair; it also proves that positioning theory plays a considerable role in relation to both repair initiation by teachers and students as well as their reactions to it. Thus, the participants’ positioning has a significant effect on why some repair moves are likely to occur while others are not.

Recurrent events experienced by individual units or systems occur in many fields. The main target of this thesis is to develop formal tests for certain features of recurrent event processes, and to discuss their properties. In particular, carryover effects and time trends are considered. The former is related to clustering of events together in time, and the latter refers to a tendency for the rate of event occurrence to change over time in some systematic way. Score tests are developed for models incorporating carryover effects or time trends. The tests considered are easily interpreted and based on simple models but have good robustness properties against a range of carryover and trend alternatives. Asymptotic properties of test statistics are discussed when the number of processes approaches infinity as well as when one process is under observation for a long time. In applications involving multiple systems or individuals, heterogeneity is often apparent, and there is a need for tests developed for such cases. Allowance for heterogeneity is, therefore, considered. Methods are applied to data sets from industry and medicine. The results are supported by simulation studies.
