A weighted combination of attributes including but not limited to color, shape, pattern, brand, style, size, and material may be used to rank items when searching for similar items of a given category on an ecommerce system website. The weights on each attribute may be optimized by using feedback from users, the feedback indicating the importance of each attribute to a purchaser when searching for similar items of various categories. Alternatively, click-through patterns from the ecommerce system website can be mined and used to optimize the importance of each attribute to users by item category. The optimum attribute weights for that items category are used to rank the results in a search for similar items in that category.

Search term ranking algorithms can be generated and updated based on customer settings, such as where a ranking algorithm is modeled as a combination function of different ranking factors. An end user of a search system provides personalized preferences for weighted attributes, generally or for a single instance of the query. The user also can indicate the relative importance of one or more ranking factors by specifying different weights to the factors. Ranking factors can specify document attributes, such as document title, document body, document page rank, etc. Based on the attribute weights and the received user query, a ranking algorithm function will produce the relevant value for each document corresponding to the user preferences and personalization configurations.

A method of utilizing and inventorying variable attributes for rooms associated with Hotels and other similar services. A database comprising multiple data sets is compiled, where the data sets available may comprise any of the following: room availability; room attributes; attribute weight; and Guest weight. The attribute weight reflects the perceived value of the attributes for a particular room. The Guest weight reflects the perceived value of the Guest as a continued business relationship. The data sets are combined, with the information comprising an inventory of data that is similar to available assets. When a room is requested with certain attributes, higher weighted Guests will be given rooms with a higher weight, and lower weighted guests are matched with rooms having a lower attribute weight. The system can continuously shuffle all rooms, prior to the Guest actually checking in, so as to maximize Guest satisfaction and revenue to the Hotel.

A method of optimizing parameter values in a process for producing a product, which process is essentially controlled by a set of parameters affecting a set of properties characterizing the product. The method uses an analytic hierarchy process (AHP) to associate a weight with each property according to its relative importance to obtain desired product characteristics. The method also uses parameter data and measured property data from a required number of experimental runs of the process, from which data property behavior relations between each property and the parameters are statistically established, which relations give estimated property values. Using the property weights, a process goal function is established, which is expressed in terms of weighted deviations between the estimated property values and the corresponding goal values for the properties. Finally, the process goal function is minimized in order to generate a set of optimal parameter values for the process.
