Browsers are one of the keys to internet security. Actually, I suppose they're really more like the car than the key. After all, they're the vehicle we use to travel around the web. Occasionally an unwanted passenger jumps on board though, and could even carjack your browser - taking you somewhere you don't want to be.
Level 1 and 2 were included as part of scope of supply of main process equipment under supplier specifications. Level 3 was specified by HYLSA and contracted to a software development oriented supplier. Level 4 was handled in a particular way, since HYLSA already had in operation a Production Control System, developed in house which schedules and track material for process lines from Melt Shop and Hot Strip Mill # 1 (ingot based) trough Cold Mills and Batch Annealing. MIS group modified that system in order to accommodate scheduling and tracking for Hot Strip Mill # 2 (CSP) which supplies material in parallel with existing Hot Strip Mill # 1. Phase 2 operation has imposed requirements that demanded flexible yet speedy interaction with Level 3 by facing changes to scheduling caused by tight coordination in operation between CSP Melt Shop and Mill.
PRODUCTION PLANNING AND SCHEDULING. Production Planning and Scheduling is based on Shop Orders, which are coil production batches (built from Customer Orders) required from CSP Plant considering Melt Shop, Caster and Mill constraints. Shop Orders once in CSP Plant are managed by a Level 3 function, Production Coordination System. Shop Orders requires from CSP Plant what to produce but Operating personnel decide when to produce it considering operating constraints in a weekly basis. Once in production, Shop Orders results in references to Level 2 Process Control Systems and actual production is sent back to Level 4 Production Planning System for coil tracking in next processing lines.
Hopefully one day you won't have to make this trade-off that is so undesirable. However, until then, you don't need to be an experienced computer user in order to do some experimenting and educate yourself about which settings to use. In fact, the first time you have to fix your computer after becoming infected you'll understand why you should have spent a couple of hours learning about settings. The last factor when it comes to security for your browser is proper usage. Ask yourself whether or not you take "safe browsing" into consideration. Many websites will ask you to download those ActiveX controls (which are little programs), adware, dialers, and other content that is considered to be dynamic. Do you simply trust the source or do you want to find out will happen when you say yes to these prompts? Trusting is okay but you should keep your eyes open when you do any trusting.
INFORMATION AND INTRANET Collected data is used for several purposes: * Production Reports * Quality Reports * Product and Process History Production and Quality reports are accessed trough Intranet while History is accessed by process engineers using standard data base retrieve software. An Intranet Server is installed in order to allow access to CSP Plant data by using standard Web Browser, the same one used to access Internet. This data access method results in a more easy way to deploy, maintain, set up and use of CSP Plant information since applications are installed in only one machine, the Intranet Server and customers only need to set up one application in their computers, the Web Browser. Web Browser applications allow not only to show data but also charts, pictures and snapshots or live video in a very easy way.
CONCLUSIONS Modern Steel Plants benefit from high performance automated equipment that hooks up easily to plant wide high-speed communication networks. Level 1 and Level 2 are dependent on particular process equipment design and operation. Level 3 and Level 4 are dependent on plant production and operation practices. These levels are more sensitive to changes because of customer and market requirements change at faster pace than process does.
Production Control includes planning, scheduling, quality management and material tracking functions. Different plants allocate these functions in different ways, some of them allocate all of them in Level 3, and some others spread them over Level 3 and Level 4. Use of information technology based on Intranet and Web Browser technologies allows all level plant personnel to access data in a simpler and more efficient way. HYLSA have used successfully available industry standards in automation, information technology and digital communications to obtain benefits on Operational and Production Control. At the end, the wise use of all of these technologies when tied to business objectives helps steel plants to maintain its competitive position in the market.
