Each row of the matrix represents an attribute and the matrix columns matrice de opțiuni the various options alternative features, levels of service, benefits of that particular row attribute.
The cost points may reflect the actual price in currency, say, of a consumer or industrial product option, or, more commonly in service applications, the relative costs to the supplier of delivering the different benefit options.
This would be twice matrice de opțiuni cost of improving from 6—10 days wait for spare parts to a day wait. Respondents complete a series of tasks on this matrix.
Typically there are a minimum of three prioritisation stages and rarely more than five. These priorities can be used to create market models that estimate potential market share of alternative product or service specifications.

More recently this single stage budget allocation approach matrice de opțiuni been used by many manufacturers on their web-sites to collect a given respondents preferred specification having been shown the costs of different options. Matrice de opțiuni this single budget allocation, without the multiple prioritisation stages, is a part of some variants of modern conjoint trade-off analysis. The algorithms required for the modelling predictions of SIMALTO data enabling potential market share calculations and needs-based analysis were first created in the early s, with major improvements and extended capabilities introduced in Rather a variant of Brand-Price Trade-Off is used.
Total specification price or cost is not treated as one of many specification variables, as in conjoint studies, but treated mainly as a constraint.

These tools include the various forms of conjoint trade-off, discrete choice modelling and brand-price trade off approaches. The larger than usual paper size was required to comfortably show all options simultaneously to the respondent.
Respondents used different coloured pens to indicate their different stages of priorities. However, in studies that have fairly simple options with short descriptions of alternatives, e. Studies including attributes where differences between options require more detailed explanations, perhaps with illustrations, mean that attributes might be a practical limit.
This reduces data collection costs considerably but has the disadvantage that the whole of a matrix with 10 or more attributes cannot be viewed simultaneously without câștigați bani pe Internet cu o investiție de 10 the matrix on the screen.
The sequential process of building up a specification reflects real life evaluation of products or services. Simply counting how many respondents choose a particular option in preference to another provides an unambiguous quantification of each option's relative popularity. The method most frequently used matrice de opțiuni based on expert system rules linked to neural net logic and genetic algorithm theory.
Examples of these rules applied to competing specifications facing an individual respondent: For similarly priced specifications, the one that contains more of the respondents high value priority options and fewer of his low value priority options is likely to be the one most preferred.
The specification that is priced costed nearest the price he wanted to pay for this product is likely to be preferred to those that are either over-specified, and therefore likely to be too expensive, or those that are under-specified and therefore unlikely to satisfy his needs.

That is the difference between the value of the specification to him compared to the price it is sold at. Because the respondent evaluates each option on many occasions and the modeling uses these several data inputs, the variance of reported findings is less than matrice de opțiuni with individual observations. Simulation preference predictions are made for each respondent individually — matrice de opțiuni is no averaging of forecasts across respondents required by methods that can only show a subset of all the options to an individual respondent when there are more than 7 or 8 attributes.
Needs-based cluster analysis is carried out directly on individual respondents and does not require complex statistical Bayesian analyses. Product price or service cost is not treated as a trade-off variable but rather price and cost are more considered to be a constraint, matrice de opțiuni reflecting the real-life situation.
Brand value, if included in a survey, is not simply treated as another trade-off attribute. In many product fields most major manufacturers can produce most of the options on the SIMALTO matrix, so to trade off a brand with one or more options is not realistic. But brand does have a relative value due to brand image factors, promotion, availability, customer inertia etc.
Research findings can be directly linked to raw data. For a product or service with many features, designing the Simalto matrix can be time-consuming.

With too many options, in a web-based survey some respondents matrice de opțiuni not read all the possible options as they will have to scroll down. Respondents may feel forced to think about issues they would otherwise not pay attention to.
