Domino is a game of chance played with dominoes. A domino is a small, flat, thumb-sized rectangular block bearing from one to six pips or dots: 28 such tiles form a complete set. They are usually arranged in lines or angular patterns on a flat surface, with each player drawing seven from the stock (also called the boneyard) and placing them on their domino board. The goal of the game is to get as many of your tiles into play as possible, before your opponent does.
While Domino’s has seen an increase in sales, it has also faced rising operating expenses. The company has had to raise worker pay, cleaning supplies and ingredient costs during the pandemic. This may have had an effect on the company’s profits.
Domino’s was founded by Tom Monaghan in Ann Arbor, Michigan, in 1960. After graduating from high school, he worked in various restaurants and pizza shops before starting his own business. He aimed to create a pizza chain that was both fast and affordable, and he named it Domino’s Pizza after his childhood idol, actor Nicholas Cage.
The word domino originates from a Latin verb meaning to dominate. The word’s meaning evolved to refer to a long hooded cloak worn over a mask during carnival season or at a masquerade. The name subsequently changed to the modern sense of playing piece with a black and ivory face, recalling the priest’s domino cape contrasting with his white surplice.
In chemical industrial clusters, domino effects often involve multiple plants belonging to different companies. Moreover, the hazards possibly leading to domino effects at one plant depend on the decisions of other companies situated within the same cluster. Therefore, protection strategies for domino effects must be adapted to the decisions of each corporation.
To model and manage these effects, it is important to understand the process and the chain of events that could lead to an accident. This can be accomplished by using a systems engineering approach. This approach is a comprehensive method of analyzing an entire system, including its components and their interactions.
A good way to model an accident sequence is by building a dynamic Bayesian network (DBN). This method can help improve the inaccuracy caused by simple assumptions used in traditional BN analysis, such as independent events and random selection of target units. Furthermore, a DBN can incorporate temporal dependence in the modeling of a domino effect.
A protection strategy for domino effects includes inherent safety design, applying safety barriers and enhancing the capability of emergency response teams. A protection strategy should also consider the cost of the protection measures and potential avoided losses. Janssens et al. (2015) developed an optimization method to allocate safety barriers in chemical industrial sites based on the risk of fire escalation. This can reduce the failure time and allow for more time for emergency response actions, which will minimize the consequences of a domino effect caused by a fire.
