“…While further work is required to evaluate and refine our particular approach in response to learner feedback, we anticipate that our visual representation will enable learners to reflect on the match (or otherwise) between what they meant and the picture that their use of temporal expressions produced. Externalising and reflecting on your knowledge is widely regarded as an important step in learning (Chen, Cannon et al ., 2005; Lehtonen, Appelqvist et al ., 2002; Flanagan, Eckert et al , 2007), and we would expect the same to be true in this challenging area of language learning.…”

This paper reports on the development of a prototype tool which shows how learners can be helped to reflect upon the accuracy of their writing. Analysis of samples of freely written texts by intermediate and advanced learners of English as a foreign language (EFL) showed evidence of weakness in the use of tense and aspect. Computational discourse modelling techniques were applied to the data to generate semantic models of fragments of the narratives with particular focus on their temporal structure. These models have been converted into dynamic graphical representations of the temporal relationships between discourse events as the narratives are written. The system also provides access to the ontology devised to model individual events and this offers learners insights into the events' semantic properties. These techniques provide the basis for a stimulating learning tool capable of capturing key elements of written narratives, and prompting learners' awareness of language use, particularly tense and aspect.

Time–Cost Schedules and Project–Threats Indication

One of the most common disciplines in a business or economic project is timing and resource review. Despite the frequency of use, the level of sophistication is not high enough to maintain its level of importance. Exceeding deadlines and non-compliance with contractual costs is more than common. Moreover, there are projects where uncertainties are a naturally accompanying phenomenon. Research projects, implementation of solutions in a time-limited situation, or in an environment of limited knowledge creates risk. Any project proposal faces future realization risks when its planning management does not know with certainty where the current risks and uncertainties may come from. Decision-making, risk management dynamics, and simulations have developed in recent decades into an erudite and useful discipline. The aim is to indicate how much of the time–cost schedule proposal is stable, controllable, and economically feasible. The approach is based on the idea that modern resource scheduling requires nonlinear dynamic calculating models and simulations. The methodology presented is based on the dynamics of underlying physical and economic processes that form a spatial pattern of a time series. The article’s objective is devoted to the early indication of a dynamic project schedule’s instability and predisposition to bifurcation and chaos. In other words, the aim is to show not only what will happen but how diverse and damaging the project may become in the future.

“…The job shop scheduling problem is the problem of finding a way to schedule a number of operations, such that the last operation is completed as soon as possible. Here an operation is a task that must be executed on a resource, called the machine (Lennartz,1999).In job shop scheduling, any job can be processed on any machine in an order that is predetermined but can be different for each job (Lehtonen et al, 2003).…”

The planning engineering is considered a vital part in the industrial operations series that leads to achieve the proposed production plan. Because of scientific advancement and technical development in the industrial field, the managements of the companies and job shops start to automate the engineering and management activities for the aim of quickness and accuracy in making proper decisions for the production process in order to get final product in a better quality and minimum cost. This is achieved by the future estimation of production plan. The research concern with evaluating the size of work arrival to the manufacturing shops and determining the amount of capacity that is required to perform these evaluated job volume in a manner that warrant decreasing the cost of orders and machines waiting. To achieve this aim, a constructation of simulation system by using Visual Basic computer program that helps the user in future estimation of job volume and determination of the best process capacity of the job shop which through it the job can be accomplished. Actual and realistic data that are collected from the documents of Electrical Industrial Company (EICO) factories is in random orders arriving to factories in one man-day and also the actual time to perform number of these orders. Through the designed software which is used as a tool for simulating of the target production system in this research, the best simulation daily process capacity was obtained for the job shop to be 130 hr per day where as, it achieved the minimum value of the total cost. There is a great effect for this increment of job shop daily process capacity in decrement of waiting of orders and this lead to optimal exploitation for these presented capacities. To verify simulation results and obtain the optimum selection for these results, the researcher used a modern technique called R-Technique or Response Surface Methodology (RSM), which the desirability function which is used as a dual-purpose standard to obtain the optimum value of job shop process capacity.
