Where Is FatBoy ?

Goodbye Sydney, airline flight home today is on MH122 with this Airbus A330-300. Pre-flight drinks of orange juice. Appetizer of Prawn with mango and avocado timbale, with baby rocket salad. Main span of Ayam Masak Merah, slow braised chicken in sweet tomato gravy with tomato rice and sauteed vegetables. I had formed this cake before in earlier plane tickets and it it actually quite good and tasty. Weiss Glaciers Cream offered with this trip sector always.

Note we’ve an inequality here rather than an equality. This implies that people may produce more of some quality of ore than we are in need of. In fact we’ve the overall rule: given a selection between an equality and an inequality choose the inequality. 24 and there are no ideals of x and y which satisfy all three equations (the problem is therefore reported to be “over-constrained”).

The reason for this general guideline is that choosing an inequality rather than an equality provides us more versatility in optimising (maximising or minimising) the objective (deciding values for the decision variables that optimise the objective). Essentially an algorithm (for a specific model) is a couple of instructions which, when adopted in a step-by-step fashion, will create a numerical solution to that model.

You will dsicover some examples of algorithms later in this Management Course.. OR is the representation of real-world systems by numerical models together with the use of quantitative methods (algorithms) for solving such models, with a view to optimising. A very important factor I wish to emphasise about OR is that it typically deals with decision problems.

You will see examples of the many different types of decision problem that can be tackled using OR. In general terms we can regard OR as being the application of medical methods/thinking to decision making. Indeed it could be argued that although OR is imperfect it offers the best available approach to making a particular decision in many instances (which is not saying that using OR will produce the right decision). You can develop your own judgement concerning whether OR is preferable to this process or not. Drawing on our experience with both Mines problem we can identify the phases that a (real-world) OR task might go through.

It may be that a problem can be modelled in differing ways, and the choice of the correct model may be imperative to the success of the OR task. In addition to algorithmic considerations for solving the model (i.e. can we solve our model numerically?) we must also consider the availability and accuracy of the real-world data that is required as input to the model. Note that the “data barrier” (“we don’t possess the info!!!”) can show up here, if people want to obstruct the task particularly.

Often data can be gathered/estimated, particularly if the potential benefits from the project are large enough. You will also find, should you choose much OR in the real-world, that some environments are naturally data-poor, this is the data is of poor quality or nonexistent and some environments are naturally data-rich.

As examples of this chapel location research (a data-poor environment) and an international airport check- in desk allocation study (a data-rich environment). This presssing problem of the data environment make a difference the model that you build. If you think that certain data can’t ever (realistically) be obtained there could very well be little point in building a model that uses such data. Standard computer deals, or developed algorithms specially, can be used to solve the model (as mentioned above). In practice, a “solution” often requires lots of solutions under differing assumptions to determine sensitivity. For instance, imagine if we vary the insight data (which will be inaccurate anyhow), how will this impact the beliefs of the decision variables then?

Questions of this type are generally known as “what if” questions nowadays. This stage may involve the implementation of the results of the analysis or the implementation of the algorithm for solving the model as an functional tool (usually in some type of computer package). In the beginning detailed instructions on what needs to be done (including time schedules) to put into action the results must be released. In the second instance operating manuals and training techniques should be produced for the effective use of the algorithm as an functional tool.

It is thought that lots of of the OR projects which successfully pass through the first four phases given above fail at the execution stage (i.e. the task that is done doesn’t have a lasting effect). Because of this one topic that has received attention in conditions of bringing an OR task to an effective conclusion (in conditions of implementation) is the problem of client involvement.
