1An industrial engineer conducts a time study on a metal-stamping operation. The observed average cycle time is 2.40 minutes, the operator's performance rating is evaluated at 110% (1.10), and the total allowance factor for personal needs, basic fatigue, and unavoidable delays is 15% (0.15). What is the standard time (Ts) for this operation in minutes?
A.3.04 min
B.2.64 min
C.2.76 min
D.3.11 min
Explanation: Normal time is calculated by multiplying the observed time by the performance rating: Tn = 2.40 min × 1.10 = 2.64 min. Standard time is then obtained by applying the allowance factor to normal time: Ts = Tn × (1 + S) = 2.64 min × (1 + 0.15) = 2.64 × 1.15 = 3.036 min, which rounds to 3.04 minutes.
2A manual assembly line comprises six distinct tasks with a combined total work content of 18.0 minutes. The line is configured with four sequential workstations, and line pacing is restricted by the bottleneck workstation, which has a cycle time of 5.0 minutes. What is the line balancing efficiency (E)?
A.72.0%
B.90.0%
C.10.0%
D.111.1%
Explanation: Line balancing efficiency is defined as the ratio of total work content to the total available workstation time: E = Σt_i / (n × C), where Σt_i = 18.0 minutes, n = 4 workstations, and C = 5.0 minutes. Substituting the values yields E = 18.0 / (4 × 5.0) = 18.0 / 20.0 = 0.90, or 90.0%. The remaining 10.0% represents balance delay (idle time).
3An automotive subassembly plant operates an 8-hour shift (480 minutes) with two scheduled 15-minute unpaid breaks, leaving 450 minutes of net available production time. Customer demand is established at 900 finished units per shift. What is the takt time required to synchronize production with customer demand?
A.32 seconds per unit
B.28 seconds per unit
C.30 seconds per unit
D.36 seconds per unit
Explanation: Takt time is defined as the net available operating time divided by customer demand. Net operating time in seconds is 450 minutes × 60 seconds/minute = 27,000 seconds. Dividing by the demand of 900 units yields: Takt time = 27,000 seconds / 900 units = 30 seconds per unit.
4In motion study and micromotion analysis developed by Frank and Lillian Gilbreth, fundamental hand motions are classified into Therbligs. Which of the following Therbligs is classified as an ineffective (non-productive) motion that adds no value to the workpiece and should be eliminated through workplace redesign?
A.Assemble (Ensamblar)
B.Use (Usar)
C.Reach (Alcanzar)
D.Search (Buscar)
Explanation: Therbligs are divided into effective (productive) and ineffective (non-productive) motions. Effective Therbligs directly advance the progress of work (such as Reach, Move, Grasp, Assemble, and Use). Ineffective Therbligs (such as Search, Select, Hold, Inspect, and Unavoidable Delay) add no physical value and represent wasted time caused by poor workplace layout; they should be eliminated through proper organization and pre-positioning.
5A work analyst uses the Westinghouse rating system to level an observed cycle time of 1.50 minutes. The operator's performance is graded as follows: Skill B1 (+0.11), Effort C2 (+0.02), Environmental Conditions D (0.00), and Consistency E (-0.02). What is the leveled normal time (Tn) for this operation?
A.1.665 min
B.1.500 min
C.1.725 min
D.1.335 min
Explanation: In the Westinghouse leveling system, the four performance factors are summed algebraically to determine the net adjustment: Net adjustment = +0.11 (Skill) + 0.02 (Effort) + 0.00 (Conditions) - 0.02 (Consistency) = +0.11. The overall performance factor is 1.00 + 0.11 = 1.11 (111%). Normal time is therefore Tn = Observed time × Performance factor = 1.50 min × 1.11 = 1.665 minutes.
6According to the American Society of Mechanical Engineers (ASME) standard for process flow charting (cursograma analítico), which graphical symbol represents an unplanned or planned delay (demora), such as material waiting in a buffer between processing operations?
A.Square
B.Capital letter D
C.Circle
D.Inverted triangle
Explanation: Under ASME standard process chart symbols: a Circle denotes an Operation; an Arrow represents Transportation; a Square signifies an Inspection; the Capital Letter 'D' indicates a Delay (demora / temporary wait); and an Inverted Triangle designates permanent Storage (almacenamiento).
7An industrial engineer designs a work sampling study to determine the proportion of time automated CNC mills remain idle. A pilot study estimates that machines are idle 20% of the time (p = 0.20). At a 95% confidence level (z = 1.96) and a desired absolute error margin of ±4% (e = 0.04), what is the minimum number of random observations (N) required?
A.271 observations
B.1,537 observations
C.385 observations
D.2,401 observations
Explanation: The formula for sample size in work sampling based on binomial proportions is N = (z² × p × (1 - p)) / e². Substituting the given parameters: N = (1.96² × 0.20 × 0.80) / (0.04)² = (3.8416 × 0.16) / 0.0016 = 0.614656 / 0.0016 = 384.16. Rounding up to the next integer gives 385 observations.
8Under Mexican Official Standard NOM-025-STPS-2008 (Condiciones de iluminación en los centros de trabajo), what minimum illumination level applies to visual tasks requiring fine distinction of detail (distinción fina de detalles), such as precision machining and the assembly and inspection of delicate work?
A.300 lux
B.500 lux
C.750 lux
D.1,000 lux
Explanation: Table 1 of NOM-025-STPS-2008 sets minimum levels by visual task: 200 lux for simple visual requirements, 300 lux for moderate distinction of detail, 500 lux for clear distinction of detail, 750 lux for fine distinction of detail (precision machining, assembly and inspection of delicate work, handling of small parts), 1,000 lux for high-accuracy work on small, complex parts, and 2,000 lux for highly specialized tasks.
9A manufacturing engineering team is designing a progressive assembly line. The total elemental work content is 142 seconds, and the desired production rate dictates a takt time of 40 seconds per unit. What is the theoretical minimum number of workstations (N_min), and what would be the line efficiency if physical layout constraints force the line to use 5 workstations?
A.Minimum 4 stations; efficiency is 71.0%
B.Minimum 3 stations; efficiency is 71.0%
C.Minimum 4 stations; efficiency is 88.8%
D.Minimum 4 stations; efficiency is 29.0%
Explanation: The theoretical minimum number of stations is N_min = ceil(Σt_i / Takt) = ceil(142 / 40) = ceil(3.55) = 4 workstations. If 5 workstations are implemented with a cycle time matched to takt time (C = 40 s), line efficiency is E = Σt_i / (n × C) = 142 / (5 × 40) = 142 / 200 = 0.710, or 71.0%.
10According to Ralph M. Barnes' principles of motion economy regarding workplace arrangement, where and how should tools, parts, and materials be positioned to minimize operator fatigue and motion time?
A.Grouped centrally behind the operator to keep the immediate front table completely clear
B.Pre-positioned in fixed locations within the normal and maximum horizontal reach envelopes
C.Arranged in sequential order along an elevated overhead rack requiring vertical reaches
D.Distributed evenly across the entire perimeter of the assembly table to promote whole-body stretching
Explanation: Barnes' motion economy principles dictate that tools and materials should be pre-positioned in definite, fixed locations within the worker's normal and maximum horizontal working areas. This eliminates search and select motions, allows habitual motor patterns to develop, and keeps reach distances within comfortable biomechanical boundaries.

Frequently Asked Questions

What is the EGEL Plus Ingeniería Industrial?

The EGEL Plus Ingeniería Industrial (EGEL Plus IINDU) is Ceneval's national exit examination for graduates of the Licenciatura en Ingeniería Industrial and related programs. It measures the knowledge and skills considered indispensable at the end of the degree, plus Spanish reading comprehension and indirect writing. Institutions may use the result as a graduation requirement, a titulación option or part of a course grade, under their own rules; a Testimonio does not by itself determine the award of the degree or the cédula profesional.

How many questions are on the official EGEL Plus IINDU and how long is it?

The official exam has 220 items: 160 disciplinary items (Estudio del trabajo 40, Gestión de la cadena de suministro 40, Proyectos de inversión, estratégicos y operativos 30, Sistemas operativos de manufactura y servicios 50) and 60 Lenguaje y Comunicación items (30 reading comprehension and 30 indirect writing). It is given on one day in two sessions of 4.5 hours each (9 hours). About 15% of the items are pilot items that do not count toward the result.

How is the EGEL Plus IINDU scored?

Each area and section is reported on the Índice Ceneval from 700 to 1300: 700-999 Aún no satisfactorio, 1000-1149 Satisfactorio and 1150-1300 Sobresaliente. The global result follows a conjunctive rule weighted toward the disciplinary section: Satisfactorio or better in the disciplinary section earns at least a Testimonio de Desempeño Satisfactorio, while a Testimonio de Desempeño Sobresaliente requires Sobresaliente in the disciplinary section and at least Satisfactorio in Lenguaje y Comunicación. Candidates with a global Sobresaliente who take the exam for the first time within one year of finishing the degree are eligible for the Premio Ceneval al Desempeño de Excelencia-EGEL.

Can I use a calculator or formula sheet on the EGEL Plus IINDU?

Yes. The official guide allows a non-programmable scientific calculator, which may not be shared between candidates. Ceneval also provides a formulario (formula sheet), handed out on paper or shown on the exam platform depending on the modality, and publishes it on its EGEL portal so you can study with it in advance.

Why is this practice bank in English if the official exam is in Spanish?

The official Ceneval exam is in Spanish. This bank is an independent English-language study adaptation with four-option questions, not an official translation or format simulation. Disciplinary questions and explanations are in English so you can review the engineering content. Language and communication items keep their Spanish passages and options because they test Spanish usage, and their instructions and explanations are in English.

What are the disciplinary areas of EGEL Plus IINDU?

The 160 disciplinary items are split into Estudio del trabajo (40), Gestión de la cadena de suministro (40), Proyectos de inversión, estratégicos y operativos (30) and Sistemas operativos de manufactura y servicios (50). Each of the 16 subareas has 10 items.
