Subject

In the UK, the late night culture of “clubbing” is very popular with around 40% of the key target group being students. In the UK, the average club derives around two-thirds of tis revenue from the sale of beverages, and it is therefore a vital source of profits .

New: Simulate the dancing behaviour of people in a bar or club.

When looking at Stratumseind these days, clubs and bars that were once flourishing look empty and silent. For a manager of such a bar, it may be difficult to decide what to improve to regain the glory of those golden days. Humans are complex, so their happiness and willingness to spend may depend on different factors combined in a specific way. Because of all these different factors, experimenting with them in real life is impossible work. On top of that, change in revenue might not be seen in a week, to be sure a longer observation period is needed. However, if you need to test a lot of different factors in a lot of different combinations, this takes ages.

That is where a simulation of the behaviours of the people in a bar or club might help. The simulation will make it easy to experiment with different factors, and adds the possibility to run multiple simulation in sequence. This way, certainty can be reached about the influence of a certain factor on the revenue, and managers of clubs and bars can come to decisions about what to improve to make their bar great again.

Objectives

• Main goal: assist the owner of a bar or dance hall with ideas on how to improve customer revenue.
• Construct an AI multi-agent simulation with which we can find what variables with what capacities are needed to maximize generated income.
• Analyse the reliability of such a simulation by discussing the observations of the client and the results of previous research done in this field (if any apply).
• Analyse the possibilities and shortcomings of such a simulation.

Research variables

Note: during the early phases of this project, variables are subject to change and may still be included/excluded.

General variables

Income

• Description: The amount of money spent by patrons inside the establishment during the evening/night in order to buy alcohol. Alcohol is the only product available, which has to be bought using euros as currency.

• Used in simulation: no yes
• Reasoning: kaas

Energy

• Description: All actions that a patron takes cost some energy.
• Used in simulation: no yes
• Reasoning: kaas

Constraints

Constraints are limits that are set for the simulation. Constraints are needed in order to create a working simulation. Without these constraint a simulation would prove too complex to make, therefore these constraints have been made.

Bar

• Bar cannot be remodeled or renovated
• There is only one type of alcohol/drink
• Not taking into account other bars/competitors
• Given one night with certain amount of people inside
• Bar will not sell food
• No animals are allowed
• Drinks will not expire
• The bar only has one room in which people will dance and drink

People

• People will not start fights
• People will not complain
• People will not break stuff
• People will always pay and not steal

Patron states

• Drinking: The only state that can be done simultaneously with any of the other states: In this state, the patron's alchohol will be drunk, increasing its intoxication level.
• Dancing: The patron is currently dancing and socialising with others. This actions does cost more energy than any other action.
• Talking: The patron is conversing with others, This does cost some energy.
• Buying: The patron is currently buying more alcohol for him/herself.
• Standing: In this state, the patron is inactive and unsocial. This state barely costs any energy.

Users

New (10/2): This simulator should prove useful to bar, club, dance or music events managers. Since this will help them with determining how to best get people dancing. Which for these managers in turn will mean more income. This could possible be used for other people who want to organize a personal event.

A secondary user for which this simulator might prove useful, are the people going to the bars, clubs, dance or music events. Assuming that customers spend more money when they enjoy themselves and leave when they do not, using the results of the simulator to improve bars would mean that bars become more enjoyable. This is beneficial for the customers: they will have a better time.

Alcohol behaviour and social settings

Social groups and their influence on the drinking behaviour of people in a bar

One can imagine that the composition of ones drinking group can have quite an influence on how you drink. Several studies support that indeed, the social context of a drinking occasion can impact drinking behaviour . Several studies shed light on more specific social factors and their corresponding impacts.

For starters, a larger drinking-group size is associated with heavier drinking . This seems quite logical: with more people, there are more people doing rounds, thus there is a longer time between having to get alcohol yourself while still getting a continuous supply of alcohol. Interestingly, this relationship was stronger for man than for woman . Also, man were found to consume more alcohol than woman, particularly at the beginnings of the evening. .

On top of the number of friends you take with you, the gender composition of those friends also influences drinking behaviour. A study found that both males and females consume significantly more drinks in mixed-gender groups. . There is a difference between males and females here: men consumed more drinks in groups with an equal amount of males and females and groups with men in the majority. They also consumed more drinks with in a group with men only compared to woman only.

Woman however, although they did consume more drinks in mixed-gender groups, consumed significantly fewer drinks in groups with men only than groups with woman only.

There are more differences between male and female pub-goers. One study found that male friends or acquaintances were the main sources of pressure on people to drink or drink more . According to the same paper, pressure to drink also depends on religion and gender. Another study found that indirect pressures to drink play a more significant role than direct pressures

https://serval.unil.ch/notice/serval:BIB_93F9E1EBAF0B RSOD is by far most prevalent on Saturday evenings followed by Friday evenings, usually because young people go out and do not have any work or study responsibilities the next day;

Music and its influence on the behaviour of people in a bar

Music can have quite an influence on how people behave in social settings. Most people like background music: studies have found that people spend less time drinking in bars that don’t play music . It goes even further: according to a previous study, loud music makes people drink 31% more . The reason behind this is could be that when people can not communicate due to the noise in the bar, they start focussing on drinking . Another explanation is that high sound levels may cause higher arousal, which leads the subjects to drink faster and order more drinks .

Another study links faster music to faster drinking . However, a different study links slower music to more sales. Customers stayed about the same amount of time but spent more during slow music than during normal or fast music. . An explanation for this difference is that people prefer to listen to music that moderates their state of arousal . During a relaxing activity like an afternoon beer, people prefer slow low-arousal music, while during a night out people prefer music that further heightens their state of arousal. On top of that, studies found that the genre of music matters. Jacob (2006) found that when playing drinking songs in a bar, the duration of stay and spending both are increased . Further research supported this and claimed that customers exposed to textual references to alcohol spent significantly more on alcoholic drinks than those who were not .

It was also found that in social context, people modify their bodily behaviour according to the dynamic level of the bass drum. More specifically, they move more actively and display a higher degree of tempo entrainment as the sound pressure level of the bass drum increase . This could be interesting if a correlation between dancing and alcohol could be found.

Other Factors

• Day of the week: heavy drinking occurs mostly on Saturday evenings followed by Friday evenings. This is because young people do not have any responsibilities the next day

Scent

Apart from the earlier named influences on alcohol intake, a lot of other factors can influence how people behave on a night out.

One of these factors is scent: on a night out, one may encounter many scents, both pleasant and vile. Sweating bodies, alcohol, you name it. It would seem logical that ambient scents that mask the vile odours could contribute positively to the night-time experience. A previous study confirms this: they tested the scents of orange, seawater and peppermint, and found that all scents enhanced dancing activity and improved the evaluation of the evening, music and mood . Additionally, they found that the increase in dancing coincided with an increase in temperature in the club. This may lead to the customers wanting more alcohol: if it is hot, what’s better than a cold beer to cool off?

Factors that influence how much people like a bar

Apart from knowing how to influence the alcohol intake of customers, it is important to know how to get customers. There have been a few studies that worked with focus groups in order to find out what people wanted from bars.

First of all we have security. Most bars have security, if only to dismiss all people below legal drinking age. The nature of the security presence outside a bar can be a good indicator of the level of security inside a bar. Studies found that a more formal attire offers a greater image of security . This is because people do not like going somewhere where you do not feel safe. People however wanted the security personal to look friendly as well, they did not want to feel threatened by the very security that should protect them . There is a difference here between male and female clientele: while most men belief that more formal attire offers the greatest image of security, only about 50% of woman have the same belief, while the other 50% prefer an informal attire.

The clientele is important as well. People prefer a mix of male and female clientele, with the majority liking a male-dominated place the least . This seems to corollate with the fact that people drink more in mixed-gender groups. Women like a mixed clientele more than men; men like a predominantly female clientele about as much as a mixed clientele . Males offered an explanation for their preference for mixed-gender bars: they identified woman as critical factor in the decision to select a bar . How busy it looked is also named as a critical factor in the decision to select a bar. It should not be too busy, but not to quiet either .

Then we have the seating. Opposing the stereotypical image of pub customers on barstools, the same study found that sofas are the most preferred as seating arrangement inside a venue. Seating and bar stools proved far less popular. People like relaxing and taking a break from the pushing and shoving every now and then . Woman like individual seating particularly well, but still less than sofas .

The type of venue was found to be important as well. Both men and women prefer a traditional bar, but men prefer this more than women. Women have as close second the wine bar. A Latin themed bar is least liked by both men and women .

Deliverables

State-of-the-art

A list of variables influencing behaviour at a bar setting.

A list of missing variables influencing behaviour at a bar setting.

A hypothesis on how the results our simulation would create.

A research plan detailing how to fill in the blanks of the state of the art.

Results of our research.

A minimum viable product: a simulation that can houses AI that can navigate a bar setting.

Extension of the minimum viable product trough implementing more complex behaviours found in the research.

Results out of the simulation, a set of factors and the behaviour it creates in the simulation.

Finalized wiki and conclusions.

A presentation
