1. INTRODUCTION

The paper come to present the new enhanced technological-informatics system composed from ERP software system for production planning and CFS technological system. Implementing the specific ERP software system together with technological systems the efficiency in technological resources planning is highly increased and the production management is more efficient leading to performance in parts production.

2. INFORMATION

It was developed a new software system composed from an ERP web application for technological resource management and the database. The software system and the referential technological system as flexible manufacturing cell (FMC) are forming a new technological-informatics system having specific interconnected practical features.(Popescu et al., 2007)

2.1 The block diagram of CFS-ERP system

In Fig. 1. it can be observed the block components of the technological-informatics system consisting in CFS technological system and ERP software system. The ERP software system, specifically design for production programming in flexible machining cells is formed from .NET web application and SQL database. The two main components of the software system are running on hardware servers, recommended separately, on web server respectively on database server. The ERP software system is interconnected with the CFS technological system in the Enterprise intranet. Accessing the specific features of the ERP software system, it become possible to generate the needed reports for launching the parts production. When the production is started the CFS technicians, monitoring the production status can update the number of manufactured parts by accessing a specific feature of the Production Planning module. In the diagram it can be observed the main possibility of accessing the ERP software system by Client PCs, equipped with Web Browser, used for data entries and reports generating. Also in the intranet is assured the IT&C development and maintenance service for the ERP web application and the specific database. The access to ERP software system is possible also from internet connecting to the ERP for production planning modules by authentication and authorization corresponding to an username and a password assuring confidentiality of production data & controlled access.

The activities in part manufacturing from CFS level are bring together with the preparing production activities by the same ERP modules generating efficiency and fluency in work.

2.2 The visual diagram of ERP modules

The new enhanced technological-informatics system as CFS-ERP can be observed as visual diagram of ERP modules, hardware disposal and allocated human resources in Fig. 2. The CFS technological system component consist mainly from CNC Tool Center, Industrial Robot, Conveyor and Command and Control Unit.(Nicolescu, 2007) The CFS was studied for manufacturing parts with revolution surfaces starting from bars. The ERP software system consist in a distributed structure specific to the manufacturing activities and also consist in a main core formed from the Web Server for the .NET application and database server for the SQL Server database.

[FIGURE 2 OMITTED]

The software requirements for running the ERP software system for technological resources planning in CFS are:

--Microsoft Internet Explorer (or other web browser)

--Operating System with IIS--Msft. Windows 2000 or better

--.NET Framework 2.0

--RDBMS Microsoft SQL Server 2000 or 2005

--Microsoft Excel for reports generated as excel file

--Microsoft Project for viewing the production project

--For updating and maintenance of ERP as ASP.NET web application is needed Visual Studio 2005 the Microsoft tool for .NET development.(Negara, 2004). The hardware requirements for running the ERP software system for production programming in CFS are identified according to Fig. 2.:

--User PCs as Work station terminals connected in intranet

--Internet Server (with OS Windows Server 2000 or better)

--Data Base Server for RDBMS Microsoft SQL Server 2005

2.3 The work flow of the ERP software system for CFS

The ERP software system for technological resources planning in CFS supposes a specific work flow in preparing, launching and monitoring the production. Initially in the work flow, in the Production Basis Module, is assured by the Machines Data Operator the data management for production components identified as CNC Tool Centers, Industrial Robots, Parts, Semi Parts, Machining and Tools needed in fabrication. The following step is in the Technology Module for the Technology Engineer to elaborate the part fabrication technology by selecting the specific machines, machining and tools and completing the machining parameters and uploading the machining drawing for each technological step and the manufacturing drawing for part. The Production Manager check the Machine Maintenance Operator input in Machines Status module and in function of Machines availability, elaborate and update the Production Project for specific ordered part and introduce the Start Date, the Finish Date and the number of parts to be manufactured, in Production Planning Module. The CFS Technicians accessing the Reports Module and generate the needed reports for Launching the production. The main reports are consisting in Part Manufacturing Technology, Part Technological Film, Tool Sets and Machines, Production Planned as time period and number of parts. Once the right information is available at the CFS level, the Technicians can proceed to CNC Programming, select and solicit the right tools and piece bars. The CFS Technicians are assuring the Operative Management of technological system reporting at the end of the working day the production level as number of pieces manufactured and updating in the Production Planning Module as chronologically records. If are appearing unpredicted interruptions of fabrication the initial planning has to be updated by the Production Manager noticed by the CFS Technicians who are reporting the cause and time period estimated for remediate the flow of production, as Machines functional status to the Maintenance Operator. After the production is Launched, in the Management Department it can be tracked the Production Status as level of parts manufactured and CFS Functional Status as Part Production Plan updated by accessing the Reports Module of the ERP software system for CFS becoming possible the estimation in programming new parts production. The work flow described above is containing the integration of software activities with specific technological activities in parts manufacturing in CFS systems as one expression for the new enchased technological-informatics system. The software system and the referential flexible manufacturing cell (FMC) are forming a new technological-informatics system having specific interconnected practical features. (Popescu et al., 2007) The technological-informatics integration conduct to optimizing the utilization of technological systems by improving data flow communications, data management and decreasing the time for transmitting the information to FMC production level. (Popescu et al., 2007).

The utilization of the new integrated system with specific features and emergent properties offer a clear evidence of the resources, production and machines and an increase speed of making the parts and diffusing the information flow in the system and to FMC personnel. (Popescu et al., 2007).

3. CONCLUSION

The paper presents the integration of software systems ERP and technological systems CFS as a new enhanced production system CFS-ERP technological-informatics system. The integration was presented as specific block diagram and visual diagram together with the specific work flow of the ERP software system for CFS. Implementing the new ERP-CFS technological-informatics system the resources planning efficiency in CFS is highly increased leading to performance in part production activities. Overall there were made original contributions by theorizing the new enhanced CFS-ERP system according to practical developed ERP and database.
