The theory of constraints (TOC) is a systems-management philosophy developed by Eliyahu M. Goldratt in the early 1980s. The fundamental thesis of TOC is that constraints establish the limits of performance for any system. Most organizations contain only a few core constraints. TOC advocates suggest that managers should focus on effectively managing the capacity and capability of these constraints if they are to improve the performance of their organization.
TOC challenges managers to rethink some of their fundamental assumptions about how to achieve the goals of their organizations, about what they consider productive actions, and about the real purpose of cost management. Emphasizing the need to maximize the throughput revenues earned through

The first step is to identify the constraint in the system that limits throughput or progress toward the goal.
Step 2:
Decide how to exploit the constraint(s). Decide on a plan for the primary constraint that best supports the system’s goal. This requires taking advantage of the existing capacity at the constraint, which is often wasted by making and selling the wrong products, and by improper policies and procedures for scheduling and controlling the constraint.
Step 3:
Subordinate everything else to the above decision. Alter or manage the system’s policies, processes, and/or other resources to support the above decisions. Management directs its efforts towards improving the performance of the constraining task or activity and any other task or activity that directly affects the constraining task or activity.
Step 4:
Elevate the constraint(s). Add capacity or otherwise change the status of the original resources as the dominating primary constraint. In this step, additional capacity is obtained that will increase (elevate) the overall output of the constraining task or activity. This differs from step 2 in that the added output comes from additional purchased capacity, such as buying a second machine, tool, or implementing new

The solidified part is ejected out of the mould to complete the process.
A mould is formed into the geometric shape of desired part. Molten metal is then poured into the mould; the mould holds this material in shape as it solidifies.
PROCESS IN CASTING DEPARTMENT:
Initially a prototype of the design is created which is called as the “Master”. This master is made of Silver metal.
After the master pieces are created, moulds are created using rubber for each master piece.
Wax is poured into the mould using a machine and the wax takes the shape of the design and final wax piece is formed.
A wax tree is created using the wax pieces and the wax tree is placed in the cylindrical flask.
Then investment powder is poured into the flask and the flasks are burned so that the wax is melted and investment powder becomes harder.
Next the flask is put in a casting machine where gold is poured and finally wax tree with gold is formed inside. Later the investment powder is washed with a machine and the final gold wax tree is taken out from the flask.
Next cutting of the gold pieces from the wax piece is done and
The Shang Dynasty invented and, over the years, perfected the technique of casting a bronze vessel from a clay mold assembly, which this wine vessel has also been made from using those techniques (Cantor). This mold was formed around a model of the vessel and was then cut into sections that were carved or impressed in the desired design, in this case the braided or grid design, on the inner or outer surfaces. The decorated clay piece-mold was then fired and reassembled around a clay core. Small bronze spacers were used to hold the piece-mold and the clay core apart. Then, molten bronze was poured into the mold. Using this piece-mold casting technique helped the bronze worker to achieve greater sharpness and definition in any intricate design
In The Goal: A process of ongoing improvement, Eliyahu Goldratt uses a form of literature that can be used even in today’s society to introduce his business theory of constraints. This theory is based on a chain with shortfall link in it. Basically, when analyzing any multipart system at any specific time, you will find the area of the system has a limited ability to maximize its goal. In order for this system to accomplish significant improvement it’s necessary to identify the constraint and redefine the system. Goldratt offers a great deal of information that is so basic to today’s management system that any who reads could absolutely benefit from.
This new form was called hydraulic die-forming. Hydraulic stems from the Greek word hydro meaning water and aulos meaning tube (McCreight, 2004). In today’s society, hydraulic pressing and stamping of dies are used for everything from making small pots and pans to the more extravagant automobile body models. Another use that has recently developed is the more artistic use of, producing form in silver and gold. In order to achieve this smaller, cheaper scale of die-forming experiment were conducted by Richard Thomas and Ruth Girard, which eventually led to the development of the pourable epoxy steel...

Any company is unable to manufacture a 100%. Therefore, people should really focus on the constraints, in a way that it will prevent a failure that will damage the entire system. Bottlenecks are the key in every plant, because it will determine the activity that will create a profit and maximize the business output.

Special effects makeup began with prosthetics and physical application, later evolving to mechanical apparatus concealed within the makeup, and eventually sensor compatible visual masterpieces. Various tools can be used to sculpt and design prosthetics and potential SFX possibilities. Some prosthetics were hand carved, cast, and then molded. There are elaborate processes that take multiple attempts, heaps of time, and an incredible amount of patience. There is a wide array of tools that can be used to help an artist sculpt. There are metal tools, plastic tools, and wooden tools. All of these tools have a specific use and a specific medium that they are compatible with. These tools can be used to mold clay, sculpt prosthetics, life cast, and
“These unique creations are the results of collaborative efforts between MMDC and the artisans. We work with creative metallurgy artisans to create these unique pieces. Autonomy is the core of MMDC designs. MMDC retains absolute control from conception through production phases of every project. Every piece is handcrafted to our uncompromising standards. Every detail is made and assembled by hand to match our extreme standards.

Replica molding is a process that transfers a pattern from a rigid or elastomeric mold into another material by using a liquid which gets solidified when it comes in contact with the mold. Replica molding can be broken down into three subfields namely microtransfer molding, micromolding in capillaries and UV-molding.
According to the textbook Eli Goldcratt implemented the Theory of Constraints (TOC). TOC is defined as the business approach to improve production, distribution and project management. (Jacobs, 2013) Goldcratt’s instituted a 5 step process to improve and assess current operations and productions. Goldcratt’s stated the following are rules for the management of constraints which include: “to identify the system constraints and weakness; decide how to exploit the constraints; subordinate everything else to that decision; elevate the system constraints if previous steps are broken start the process over again.” (Jacobs, 2013) By defining the issues proper measurements can be
The process is six very simple and easy steps. To start, you must identify the problem or need. That pretty much means you write down why you need to make this product or improve on something that was already created. In the example of my earbud holder, my earphones are always getting tangled when they’re in my pocket or even just laying around my room, so I need a holder that can fit in my pocket and prevents them from getting damaged. The second step is explore and research. This means you look up examples of your product that have already been made, or examples of what you want to make. For me, I looked up examples of earbud holders and clipart of owls that I wanted to base my design on. The next two steps is where most of the work comes in. The third step is design, imagine, plan, sketch etc. For this step, you want to draw or sketch out what you want your product to look like, which real functioning measurements, to prevent making your product the wrong size. Next, you create or build your product. In my case, this is when I went to TinkerCAD and made my 3D object on the computer, once I was done with it I turned it in, to be printed. This leads to the fifth step, trying out or testing your made product. This is when I tried wrapping different types of earbuds using my holder. My worked good therefore I had no need for the sixth step, which
