Oil material supplies in the oil fields' production and construction plays an important role. It is significant to manage the materials using the theory and method of ERP. In this paper, with the use of computer and network information technology, we research and developed the ERP system based on WEB in logistics management of a petroleum company. It is actualized to plan, organize and control the...
The web-based autonomous learning is gaining momentum. Despite the abundant learning resources and the incomparable learning freedom it offers, the brand-new learning environment poses problems such as the establishment of learning goals, the designing of learning plans, the monitoring of learning processes and the evaluation of learning outcomes, which might create obstacles for successful web-based...
This paper on one hand demonstrates innovative ideas in old cities' renovation both from improving infrastructural facilities and preserving original life style. On the other hand, it theoretically probes into current ideas of old cities' renovation in China.
MRP (Material Requirements Planning) is mainly applied in the stock control of dependence requirement i.e. relevant requirement which can decrease the stock level significantly. This paper designs a kind of MRP system that can concerns the production with guarantee period by using Wagner-Whitin Algorithm.
Systematic layout planning as the facility layout and the design of the traditional methods in the production system has been widely used, but not a lot of applications in forestry production systems. In this paper, in accordance with operational procedures yards and related information, and a combination of Heilongjiang Province, the actual situation yards try to apply SLP method to the overall layout...
Shopfloor reality shows that many companies with complex discrete production systems have not yet found a satisfying approach to production control. Even though a large variety of theoretical approaches exists in literature, many companies do not engineer an individual production control strategy (PCS), but stick to sub-optimal standard logic provided by their Enterprise Resource Planning (ERP) software...
The purpose of this paper is to formulate a mixed integer goal programming (MIGP) model to assist in reverse logistics network planning. The objective is to minimize the total cost (callback cost, transportation cost, operation cost, fixed cost for new facilities, revenues) and the environmental affects. The proposed model assists in determining the facility location and goods flows allocation in...
Earned value method (EVM) is a basic approach of project cost management. However, this method did not be effectively used in construction project cost management. In accordance with national planning, valuation with bill quantity (VBQ) will be the main valuation mode of construction project in future. According to Code of valuation with bill quantity of construction works (GB50500-2008) and the requirements...
Curriculum sequencing is one of the most appealing challenges in Web-based learning environments: the success of a course mainly depends on the system capability to automatically adapt the learning material to the student's educational needs. Here we address the problem of how to compare and to test different curriculum sequencing algorithms in order to reason about them in a self-contained and homogeneous...
The operation of grey numbers is a basic problem of Grey System Theory. Considering the situation of the increase of the grey critical procedures when we use the classic grey number to calculate under deficiencies in the information, the paper made use of standard grey numbers and classic mathematic calculation methods to get the grey critical path, building a new grey critical path method to identify...
Each year, there are kinds of new diseases or natural disasters that break out around the world. And, the emergency logistics system plays an important role in the process of fighting against these diseases and natural disasters. How to evaluate and optimize the emergency logistics system in contingencies is becoming the hot researching topic. This article establishes the set pair analysis model (SPAM)...
Studies into dynamic facial expressions tend to make use of experimental methods based on objectively manipulated stimuli. New techniques for displaying increasingly realistic facial movement and methods of measuring observer responses are typical of computer animation and psychology facial expression research. However, few projects focus on the artistic nature of performance production. Instead,...
This paper focuses on a batch manufacturing system with multiple industrial robots. In this system, material-handling robots (MHRs) and material-processing robots (MPRs) are operating. Inappropriate operations of these robots might cause a bottleneck. In addition, a bottleneck is a constraint that dominates the entire system performance, that is, the productivity. Therefore, for an efficient system,...
An SCORM compliant system called Aprend-e (e-learning in Spanish) has been developed and implanted at Comisio??n Federal de Electricidad (CFE) to build a collection of training objects for electric power operators. Aprend-e includes an editor and a repository of learning objects (LOs). LOs prepared with the editor have been executed with a SCORM compliant LMS with positive results. The editor is implemented...
Recently, there has been considerable focus on incorporating the concept of sustainability into academic curricula across the United States. In keeping with this trend, Georgia Southern University has sought to introduce a minor in sustainability that will be offered to students on campus. This aforementioned effort has been presented in this paper though the development of a systematic methodology...
Actually, the most important challenge of distance learning environments is taking into account the specific and particular characteristics of each student. A dynamical accompaniment of students, during the course, allows one to consider these aspects and consequently adapts the content presentation to learning style, behavior, rhythm and knowledge of each student. This problem has been divided in...
Minimization of the operational costs, flexibility of the labor force and efficiency of all processes are increasingly important issues for every warehouse. Of all processes, order picking is recognized to be the most costly activity and therefore tends to get the most attention. Key objectives in designing an order picking operation include increases in productivity, reduction of cycle time, and...
This paper considers the problem of planning the logistics of distributing medication to points of dispensing (PODs), which will give medication to the public. Previous work on a two-stage routing and scheduling approach showed that it can generate solutions with reasonable minimum slack. This paper presents a delivery volume improvement algorithm that can increase the minimum slack of a given solution.
Distance Education today is one of the most commonly used types of educational delivery method. Almost every major and medium size university around the world has some kind of distance education services, regardless of the subjects taught. In this paper, I intend to discuss instruction such as seminars, lectures and direct classroom instruction which can be shared by distant institutions. Time differences...
Streetscape is a basic carrier of city image, while it presents the structure of urban planning and construction. By analyzing of the character of streetscape's composing system, this paper is illustrated by two aspects of space guiding and specific performance. In first aspect, integrative targets are set, and principles are given to improve the street interface. In the other aspect, with projects...
