A Preliminary Model of Expert Programming
نویسندگان
چکیده
Expert programming involves the manipulation of large amounts of memory, including external memory represented on a display, semantic memory for expert knowledge, and episodic memory about what has transpired during a particular programming session. We present a computational cognitive model that emulates several minutes of expert, naturalistic programming behavior. The model has three high-level components: knowledge, an underlying cognitive architecture, and mechanisms that allow the architecture to manipulate the knowledge. To illustrate these components we trace the model on two related episodes of behavior. In the first episode, the programmer acquires information from the display. Then, in the second episode, she recalls something and scrolls through previous screens until she reaches the display from the first episode. Emulating this behavior requires the interaction of external, expert, and episodic knowledge, the encoding of episodic knowledge as carried out by the architecture, and mechanisms for selecting goals, attending to the display, and probing long-term memory.

The optimal warehouse capacity: A queuing-based fuzzy programming approach
Among the various existing models for the warehousing management, the simultaneous use of private and public warehouses is as the most well-known one. The purpose of this article is to develop a queuing theory-based model for determining the optimal capacity of private warehouse in order to minimize the total corresponding costs. In the proposed model, the available space and budget to create a...
متن کاملMeasuring a Dynamic Efficiency Based on MONLP Model under DEA Control
Data envelopment analysis (DEA) is a common technique in measuring the relative efficiency of a set of decision making units (DMUs) with multiple inputs and multiple outputs. Standard DEA models are quite limited models, in the sense that they do not consider a DMU at different times. To resolve this problem, DEA models with dynamic structures have been proposed.In a recent pape...

To construct and understand the fundamental of relationships among elements in complicated systems on the base of expert(s) opinions, using interpretive structural modeling (ISM) methodology is beneficial. In this paper, for considering consistency rate of expert(s) and obtaining hierarchy of elements (without any loop), a modified ISM method is proposed . These experts have agreement to each...
