Managers use forecasts to inform and support their decisions. A small business owner can use sales forecasts to determine if he should hire new employees, while the chief executive of a large company can use customer research surveys to plan marketing campaigns. Unlike quantitative forecasting, numbers are not at the core of qualitative forecasting, which relies on judgment, experience and opinions.

There are two techniques used in accounting forecasting: qualitative and quantitative. Quantitative forecasting relies on historical data that can be measured and manipulated. It is best for making short-term forecasts as past trends are more likely to reoccur in the near future than in the long term.

Tourism can bring long term benefits to a destination, but it is reasonably dependent on accurate decision and forecast on elements such as tourism infrastructures and superstructures Uysal and Crompton, , such as railways, airports, highways, accommodation facilities, attractions, promotion and human resources.

On the other hand, short-term schedules also need prediction of the number of tourists" arrivals, price, promotion, distribution and staff employment as well as long term schedules and programming. Consequently, any decision for the future, needs a high degree of forecasts Sarames, Tourism industry forecasting is mainly based on three questions in general; 1. How many tourists will arrive in a given period of time in a certain destination?

Tourism demand forecasting methods in general are categorized into two main groups: qualitative methods and quantitative methods Song and Turner, In addition to the methodological aspect, qualitative methods receive little attention as they are only standard applications.

On the other hand, qualitative approaches do not necessarily require the existence of historic data since they rely on pooled expert opinions. Therefore, these methods are mostly used in studies which lack of previous data is apparent.

For example: a newly established destination, tour operator or resorts, would not have any historical data available as a consequence of being new. If there was economic or political instability in an area or region, previous data cannot be useful as much as in a stable environment. In other words, qualitative methods tend to provide reasonably good forecasts in the short term because of the familiarity of experts with ongoing changes in their field.

The qualitative methods work best when the forecasting scope is limited. The primary problem with qualitative methods is identifying experts in the appropriate fields and then getting them to agree on a common forecast. In this paper, the authors have tried to present a review of qualitative methods which are mostly used by tourism researchers. Traditional Approaches:Uysal and Crompton in categorized the traditional approaches into two main categorizes: 1 analysis of national or regional vacation surveys and 2 survey inquiries of potential visitors in tourism-generating areas.

However this study did not argue about the accuracy and details which will be provided in the results and just gave a brief definition. Kazuo Yamaguchi, in his Master thesis about the prediction of Japanese travelers to the United State of America in , compared the analysis of national and vocation survey with timed trend analysis and concluded that this approach such as quantitative approaches uses previous data and information from an available database.

Some surveys already have their own forecasts as well as past data analysis. This technique is less expensive and does not require a lot of experience in the tourism field or special analysis skills. In this study, the conclusion was more about the causes of Mediterranean attitudes and no information about the definition was provided except a brief one in the paper"s abstract. Since this method can be classified as a quantitative method, a method that has used the previous data to recognize the changes over the time uses a common methodology, and methods such as time series data analyzing.

Therefore a large number of published papers in demand forecasting have used these methodologies because time series is a common tool in predicting future demand Harvey, The second traditional approach concentrates on inquiries of potential visitors in tourismgenerating areas and fields such as resorts, railway stations, airports as well as tour operators.

This approach relies on the estimations of non-expert groups but still needs the experts" opinions for the final forecasting. In this light, Uysal and Crompton wrote, "Inquiries within a potential generating population may offer useful insights about the attitude or prevailing image of the potential market towards a tourist-receiving destination.

This survey emphasized both time and money while many believed the first technique could analyze the data with lower expense and with less time by using secondary data in comparison to the second data.

Econometric methodologies in comparison to traditional approaches use the "general-tospecific" approach which many researchers are recently applying in their research. In brief, general-to specific framework starts from a general autoregressive distributed lag model.

This model attempts to combine many variables relevant to the economic theory, and takes the form: Song et. In this case Stephen et al noted that traditional approaches seem useful while there are some reliable econometric techniques. Judgment-Aided ModelJudgment-Aided Models are one the most common methods of qualitative forecasting. These models try to gather a panel of experts and attempt to achieve a consensus among the panels about the specific problem or the case which should be forecasted.

The experts" gathering may occur by performing seminars or committee meetings. The final aim of such committee or seminar is reaching an agreed upon forecast by generating as much debate and interchange of ideas as possible. Baron in announced an application of JAM to Thailand tourism. According to his report, the scenarios were written based on an optional hypothesizes by paying attention to the inherent trends of international tourism.

Most of the scenarios in this method concentrated on political factors, economic tourism development and promotion. In terms of accuracy, Matthews, McHugh and Weber argued that, if these types of investigations are limited to pure description, they offer little scope for understanding the dynamics of tourism. In addition, this technique can be used for both forecast and educational issues while conducting a seminar; in other words, this technique can be instructive Vanhove, Another judgment-aided method is known as scenario writing.

In fact, a scenario takes into account any possible known fact and trend. In other words scenario writing is the process of constructing a hypothetical sequence of events to focus on the subject area.

Actually, the intent is to recognize what actions can be taken to influence the level of demand at each stage Uysal and Crompton, Archer, in , discussed the scenario writing.

He stated that it is not a real forecasting method, but a manner of categorizing the involved issues. This method tries to clarify on a possible and plausible future.

It can also be seen as a kind of Delphi forecasting method for group prediction. Archer also defined the three main components of the scenario-writing method A description of current situation Baseline analysis 2. At least one future image a description of the potential situation in the future 3. For each future image, at least one future path showing how the current situation could develop into the eventual future image.

Martin and Mason utilized the scenario method to analyze the two main areas of uncertainty about the future trends in the UK: the way attitudes and social values will develop and the outlook of the economy and the future rate of growth.

An example of the usage of this method specifically in tourism has been done by Schwaninger He tried to analyze the interaction between economic, political, socio-cultural, ecological and the technological aspects of tourism. Judgment-aided methods however seem similar to Delphi as both use panel comments, but with little differentiations. In judgment-aided modeling, experts discuss face-to-face, but in Delphi the comment will reach to the experts by questionnaires.

Consequently, in the Delphi model the experts have enough time to comment and they can think from different dimensions. Baron, of the Israel Tourism Administration, illustrated tourism forecasting in both the theatrical and empirical study of tourism.

He explained that prediction is a numeric estimate of what is going to happen if something specific was to occur. In addition, he defined three types of forecasting: 1 Automatic extrapolation 2 Guesstimates 3 Judgment-aided models Mr.

Bar Onalso in Judgment-aided Models emphasized this by describing this model as the best one. In the same vein he discussed forecasting methods such as short-term forecasts, Delphi technique, econometric models and tourist information systems and finally concluded by stating that "losses must be considered if mistakes are made in forecasts".

Delphi Model:The Delphi method of forecasting is the most famous qualitative forecasting method that has attracted the most attention in the tourism literature Stephen et al, The Delphi technique was first introduced by Dalkey and Helmer This method is based on the accumulated experience of experts and tries to gather a panel of experts from different disciplines to obtain a general consensus about the outcome of a future event Archer, It is in contrast with the judgment-aided method, which was explained in the previous section.

In this method, the panels do not gather in a conference or a place to discuss about the subject, they receive just the questionnaires. All participating experts are given feedback at each stage of the process and allowed to reconsider their responses before they go to the next round. The results in a Delphi technique are supposed to be interpreted as a "subjective assessment of possibility" rather than a "precise, statistical, statement about the possibility that particular events or trends may occur" Uysaland Crompton, The Delphi method has its own advantages and disadvantages.

Research directors of a Delphi survey can change the directions on their own favorites by the information they are going to fed back to the participants. This is therefore a weakness of the Delphi survey because individual decisions affect the final results.

In addition to that, a non-response situation may happen as the participants are anonymous. Finding experts as participants in a Delphi technique is also another challenging problem. In addition, in this method, experts judge and make estimates based on their own knowledge and level of expertise Uysaland Crompton In some cases the panel members or experts may not reach a general agreement Var, This method may also take several weeks and sometimes months, so it is a time consuming method Preble On the other hand, in this method, the participants are not discussing face-to-face and this causes the elimination of pressure from other participants.

An early Delphi forecast by English and Kearnan was concerned with the predicting of air travel up to the year Their forecast was quite inaccurate. They predicted that the demand of air travel will slightly decrease because of; a airport saturation; b noise control at airports; and c increased real fuel costs. In fact their prediction was accurate only to the year of , and after this year everything changed and dispersions in air travels were too high. Another example of the Delphi method is a survey which was carried out during the International Symposium on Tourism in Washington, DC, in Seely et al.

The study considered a comprehensive list of events that are likely to happen in the tourism businesses during the s. In Kibedi presented the main results which discussed the finding from different aspects: economic environment; natural resources environment; social, cultural and political environments; the technology environment; international environment; travel environment; tourism information; tourism employment and training; tourism and energy; tourism impacts; and tourism co-operation and co-ordination.

Liu in conducted another Delphi survey. He utilized the Delphi technique in predicting both domestic and international visitor arrivals, visitor to resident ratio and maximum visitor accommodation to Hawaii by the year The empirical results showed a high degree of similarities between different groups of experts who were working as panels in this research including local experts as tourist receivers and overseas tourist senders Stephen et al, Yong et al.

 Хватит врать! - крикнул Стратмор.  - Где. Хейл сдавил горло Сьюзан. - Выпустите меня, или она умрет. Тревор Стратмор заключил в своей жизни достаточно сделок, когда на кону были высочайшие ставки, чтобы понимать: Хейл взвинчен и крайне опасен. Молодой криптограф загнал себя в угол, а от противника, загнанного в угол, можно ожидать чего угодно: он действует отчаянно и непредсказуемо.

Она никогда раньше не слышала выстрелов, разве что по телевизору, но не сомневалась в том, что это был за звук. Сьюзан словно пронзило током. В панике она сразу же представила себе самое худшее.
