Introduction
Lattice production line includes a plurality of work stations, each connected to adjacent work stations by more than two conveyor belts. Each work station includes a manufacturing robot, an outer turntable with work piece storage, and an inner turntable aligned with the robot. A program is provided to operate each conveyor, turntable, and robot independently; where in parallel processing of work pieces through the system is possible. A preproduction scheduling algorithm provides for initial efficient use of lattice, while a runtime algorithm enables the lattice to respond efficiently to the occurrence of faults.
Main Body
This production line including a plurality of work stations for processing a plurality of work pieces, comprises: a first turntable means at each work station, the turntable having a central area and a plurality of radial storage sites leading to the central area, wherein work pieces are stored on the radial paths; means for rotating the first turntable to position the radial paths in selected angular orientations; the second turntable means positioned in alignment with the central area of the first turntable means, the second turntable means having radical transport means associated therewith for shifting work pieces into alignment with selected radial paths on the first turntable means; means for rotating the second turntable means independently of the first turntable; means for aligning the radial transport with selected radial paths on the first turntable means; means aligned with each work station for performing a manufacturing operation on work pieces positioned on the second turntable means; a conveyor lattice comprised of a plurality of conveyors aligned with each work station and extending to adjacent work stations, where in work pieces may be transferred selectively from one workstation to one of a plurality of work stations connected by the conveyors; and means for selecting the work station to which the work piece is transferred according to the availability of that work station for performing the manufacturing operation on the work piece (William, 1976 ).
The production line claim 1, wherein the lattice is configured with at least three conveyor belts aligned with each work station , where in the means or selecting the work station to which a work piece is transferred makes selections so that a plurality of work pieces move through the production line in parallel. The production line of claim2, where in the work pieces are parts to be assembled at the work stations and wherein the production line includes a plurality of entry and exit points so that the parts enter the lattice at a plurality of work stations and exit the lattice at a plurality of work stations. The production line of claim3, wherein the means for performing a manufacturing operation is positioned orthogonally of the first and second work stations and lastly the production line of claim 4, wherein the conveyors are belts.
For effective operation of an automated assembly line there is need for solution of a number of problems including: the desire to achieve maximum throughput efficiency; the production line should have the ability to effectively recover from breakdown failure of one or more of the elements of which the line is comprised so as to recover as soon as possible after a work station breakdown or task disruption and it is desirable to maximize concurrency. The first and the second turntables are rota table independently of one another in accordance with programmed instructions so as to align with the selected conveyors of the conveyor lattice. At each work station there is positioned a device for performing a manufacturing operation on work pieces at that station. In accordance with the process of the instant invention, each element of the production line operates independently of every other element, with each node of the lattice operating simultaneously while objects move between the nodes, wherein massive parallel processing of the work pieces takes place in accordance with optimum paths for the flow of work pieces into and through the lattice (William, 1976).
The lattice production line 10 comprises a plurality of work stations 11A-11D connected by an array of interstation conveyor belts 12A-12K. Each turntable has eight storageslots14; however the number of storage slots is not critical to the invention, but it is preferable that the number of storage slots exceeds the number of conveyor belts juxtaposed to each workstation 11. the turntable 13 has a central area in which is disposed a second turntable 16 which has thereon a conveyor belt 17, which is radically disposed to align selectively with the radial storage slots14 in the first turntable 13. The work pieces 15 are advanced in the slots 14 by conventional means, such as conveyor belts 18 or perhaps gravity or springs, to the belt 17 for positioning so that the robot 20 can perform its operations. The use of concurrency in the algorithm allows twelve tasks to be completed using four robots and two time intervals, wherein the time interval is equal to the time it takes to complete the longest task. The scheduling technique and storage capabilities prevent the possibility of deadlock improperly scheduled production chains. This is accomplished by elimination of the hold and waits condition that is necessary for a deadlock to occur (William, 1976).
Academic researchers conduct research in the social sciences, in medicine, or in public health relies on the software from spss inc. to analyze their research data and present their findings in clear and compelling fashion. Asking people about their attitudes, preferences, and behaviour and analyzing the strength of their views is central to many types of researchers. For others it provides additional context and the usefulness of the research. With survey one can: gather and analyze data for research studies, dissertations, or these; track changes in opinions on political issues across demographic groups; understand how attitudes, beliefs, and social norms important and predict behaviour; monitor attitudes and behaviours that affect community heath and the usage of heath services and lastly include information on the attitudes of subjects in clinical trials. Research builds on previous studies and provides the foundation for future ones and therefore the quality of the data and the reliability of your results are critical (Martin, 2007).
The SPSS offers products that help users create professional surveys and forms quickly and then collect data easily and accurately. It also offers products and services for every stage of the survey research process, from questionnaire design to data collection and analysis to reporting and deployment of results and we give a range of solutions including: For shorter surveys or surveys conducted by individuals, SPSS offers products that help users create professional surveys and forms quickly, and then collect data easily and accurately and therefore one can move from data collection to analysis in a single step and dimensions- for departmental surveys or for schools looking to measure and track performance or evaluate the student lifecycle for improved institutional planning, the SPSS offers the dimensions product suite. These products are fully web – enabled and support survey creation and translation, data collection by web, phone, scan forms, or mobile devices, and central data storage, as well as survey coding and analysis. The dimension products work with the most popular databases and the operating systems and incorporate features that protect respondent privacy, increase response rates, and turn data into actionable information through interactive, web- based reports or presentation slides. The SPSS survey research products are designed to work together to provide a seamless survey research process and alternatively, one can choose specific products for specific steps, and then integrate them with the existing systems. Also offer comprehensive training for the products and solutions, so one can immediately use them to full advantage, and worldwide technical support. (Martin, 2007)
The relative motivators for production line operative is that one element in business life that persists as management concern is the attention to productivity, whether supervising an expansion of the firm’s activities or cutting back on policies in response to sagging demand, a manager continually strives to draw a better return on his capital investment when this effort is directed toward the human portion of the firm. This exploratory review compares academic self- concept and self- efficacy research. From the conceptual perspective, self- concept emerges as a more complex construct incorporating both the cognitive and affective responses toward the self and is heavily influenced by social comparison. Self- efficacy, in contrast, concerns primarily cognitive judgments of one’s capabilities based on mastery criteria. Despite these differences, the two constructs demonstrate similar internal structures that are multifaceted and hierarchical (Namok, 2005).
From the methodological perspective, self- efficacy research demonstrates more consistent operational definitions, more context- specific assessment of both the construct and the outcomes, and more frequent implementation of experimental, as opposed to correlational, designs. In the past, self- concept research has used more general indexes of both self- concept and achievement and depends mostly on correlational rather than on experimental data. These differences, although not necessarily inherent in construct definitions, contribute to self- efficacy’s superior predictive and explanatory utility in the past research (Namok, 2005).
Conclusion
The productive line operative enables the employee to work effectively within the given time and requires limited attention from the manager as they are aware of what to perform and therefore the employer expects all the best from the employees and no wastage of time due to delays as the operation is at least faster. The academic research is able to get information related to beliefs, attitudes, social norms and other attributes that one needs to enquire from a given population. The spss device used by researchers enables them to save time and at the same time come up with the required information. These roles are of great help to the user as they give guidelines on what is required at the end of all the work done.
