Little JIL language

Little JIL is a process definition language to coordinate the activities of multiple people and software tools operating in a distributed environment and sharing data and resources (all those discussed previously). It is different ftom usual programming language normally used for computations. Various aspects of Little JIL language shall include mainly ... 

As stated earlier. Little JIL language has hierarchical structure and is a tree of step types, each of which can be multiply instantiated at runtime. Each leaf represents the smallest specified units of work and the tree s structure represents the way in which this work will he coordinated. As processes execute, steps go through several states. Typically, a step can he posted only when it is assigned to an agent who starts the step. Any of these said step is either successfully completed or may he terminated due to an exception. 

Typical Little JIL language representation has been shown in Fig. APIV/2.1.T1. As shown in the figure, there are a number of badges that make up a step, as well one step s possible connections to other steps,... 

From the previous discussions it is clear that Little JIL as a coordination language rests on four major components. The concept of Little JIL language has been as shown schematically in Fig. APIV/2.1.2-1. Major components are ... 

For this, each type discussed in the preceding needs to be addressed, maybe separately, by Little JIL. Therefore Little JIL language can be applied in automating FMEA/FTA for finding failure modes in large and complex systems. 

Automated FMEA and Little JIL Process Definition Language... 

In this method, automated FMEA is done with the help of process modeling in sufficient detail using Little-JIL process definition language (see Appendix IV). Little-JIL process definition is a hierarchy of steps, representing a single unit of work. Every step specifies all artifacts and resources it uses in its interface. A step without any substeps is called a leaf step. Each nonleaf step has a sequencing badge that indicates the execution order of its substeps. Artifacts are objects passed between different steps via four parameter types, IN, OUT, IN/OUT, and Locals parameter. In Little-JIL, resources are special kinds of artifacts for which there is contention for access [11]. 

For Little-JIL process definition language refer to Appendix IV. 

There are a few numbers of such process definition languages such as business process modeling notation (BPMN) or extensible markup language (XML). Little JIL is one of the most promising process definition languages, which shall be discussed in this part of the discussion. 

From the preceding discussions, it is clear that any process definition language has some requirements to be fulfilled so that the same can be used as process definition language. Little JIL is one of such process definition language which is powerful. So, in this part, language shall be looked into with a little depth for proper understanding of the same. 

As discussed above, there are a few characteristics a process definition language when used in computer needs to meet. These are rigorous, detailed, broad semantic, and clear understanding. These characteristics are met in the following ways by Little JIL ... 

Little JIL has been developed in a factored approach that allows the core coordination language to be simpler and easier to understand, develop, and use. This kind of approach also allows a few aspects of process definition to be developed and evolved in independent ways. The design of Little JIL coordination features was guided by following primary principles ...

The main aim of this appendix is to bring readers attention to this powerful process language, which is very useful and helpful in automating hazard analysis and failure mode identifications. With this, the discussions on Little JIL is completed to look into another important issues of embedded controls which are now used in process control application including nuclear installations.

It is better to take a survey about the various requirements for a process definition language before taking a call on Little Julia input language (JIL) process language.
